- ovsdb: transaction: Keep one entry in the transaction history. [RH git: 7665f42d12] (#2044621)
    commit 6e13565dd32fb2cf5517f51ca06956e2052c4bba
    Author: Ilya Maximets <i.maximets@ovn.org>
    Date:   Sun Dec 19 15:09:38 2021 +0100
    
        ovsdb: transaction: Keep one entry in the transaction history.
    
        If a single transaction exceeds the size of the whole database (e.g.,
        a lot of rows got removed and new ones added), transaction history will
        be drained.  This leads to sending UUID_ZERO to the clients as the last
        transaction id in the next monitor update, because monitor doesn't
        know what was the actual last transaction id.  In case of a re-connect
        that will cause re-downloading of the whole database, since the
        client's last_id will be out of sync.
    
        One solution would be to store the last transaction ID separately
        from the actual transactions, but that will require a careful
        management in cases where database gets reset and the history needs
        to be cleared.  Keeping the one last transaction instead to avoid
        the problem.  That should not be a big concern in terms of memory
        consumption, because this last transaction will be removed from the
        history once the next transaction appeared.  This is also not a concern
        for a fast re-sync, because this last transaction will not be used
        for the monitor reply; it's either client already has it, so no need
        to send, or it's a history miss.
    
        The test updated to not check the number of atoms if there is only
        one transaction in the history.
    
        Fixes: 317b1bfd7dd3 ("ovsdb: Don't let transaction history grow larger than the database.")

- ovsdb: storage: Randomize should_snapshot checks when the minimum time passed. [RH git: abe61535ca] (#2044614)
    commit 339f97044e3c2312fbb65b932fa14a181acf40d5
    Author: Ilya Maximets <i.maximets@ovn.org>
    Date:   Mon Dec 13 16:43:33 2021 +0100
    
        ovsdb: storage: Randomize should_snapshot checks when the minimum time passed.
    
        Snapshots are scheduled for every 10-20 minutes.  It's a random value
        in this interval for each server.  Once the time is up, but the maximum
        time (24 hours) not reached yet, ovsdb will start checking if the log
        grew a lot on every iteration.  Once the growth is detected, compaction
        is triggered.
    
        OTOH, it's very common for an OVSDB cluster to not have the log growing
        very fast.  If the log didn't grow 2x in 20 minutes, the randomness of
        the initial scheduled time is gone and all the servers are checking if
        they need to create snapshot on every iteration.  And since all of them
        are part of the same cluster, their logs are growing with the same
        speed.  Once the critical mass is reached, all the servers will start
        creating snapshots at the same time.  If the database is big enough,
        that might leave the cluster unresponsive for an extended period of
        time (e.g. 10-15 seconds for OVN_Southbound database in a larger scale
        OVN deployment) until the compaction completed.
    
        Fix that by re-scheduling a quick retry if the minimal time already
        passed.  Effectively, this will work as a randomized 1-2 min delay
        between checks, so the servers will not synchronize.
    
        Scheduling function updated to not change the upper limit on quick
        reschedules to avoid delaying the snapshot creation indefinitely.
        Currently quick re-schedules are only used for the error cases, and
        there is always a 'slow' re-schedule after the successful compaction.
        So, the change of a scheduling function doesn't change the current
        behavior much.

- raft: Only allow followers to snapshot. [RH git: 915efc8c00] (#2044614)
    commit bf07cc9cdb2f37fede8c0363937f1eb9f4cfd730
    Author: Dumitru Ceara <dceara@redhat.com>
    Date:   Mon Dec 13 20:46:03 2021 +0100
    
        raft: Only allow followers to snapshot.
    
        Commit 3c2d6274bcee ("raft: Transfer leadership before creating
        snapshots.") made it such that raft leaders transfer leadership before
        snapshotting.  However, there's still the case when the next leader to
        be is in the process of snapshotting.  To avoid delays in that case too,
        we now explicitly allow snapshots only on followers.  Cluster members
        will have to wait until the current election is settled before
        snapshotting.
    
        Given the following logs taken from an OVN_Southbound 3-server cluster
        during a scale test:
    
        S1 (old leader):
          19:07:51.226Z|raft|INFO|Transferring leadership to write a snapshot.
          19:08:03.830Z|ovsdb|INFO|OVN_Southbound: Database compaction took 12601ms
          19:08:03.940Z|raft|INFO|server 8b8d is leader for term 43
    
        S2 (follower):
          19:08:00.870Z|raft|INFO|server 8b8d is leader for term 43
    
        S3 (new leader):
          19:07:51.242Z|raft|INFO|received leadership transfer from f5c9 in term 42
          19:07:51.244Z|raft|INFO|term 43: starting election
          19:08:00.805Z|ovsdb|INFO|OVN_Southbound: Database compaction took 9559ms
          19:08:00.869Z|raft|INFO|term 43: elected leader by 2+ of 3 servers
    
        We see that the leader to be (S3) receives the leadership transfer,
        initiates the election and immediately after starts a snapshot that
        takes ~9.5 seconds.  During this time, S2 votes for S3 electing it
        as cluster leader but S3 doesn't effectively become leader until it
        finishes snapshotting, essentially keeping the cluster without a
        leader for up to ~9.5 seconds.
    
        With the current change, S3 will delay compaction and snapshotting until
        the election is finished.
    
        The only exception is the case of single-node clusters for which we
        allow the node to snapshot regardless of role.

- python: Replace pyOpenSSL with ssl. [RH git: 0cd5867531] (#1988429)
    Currently, pyOpenSSL is half-deprecated upstream and so it's removed on
    some distributions (for example on CentOS Stream 9,
    https://issues.redhat.com/browse/CS-336), but since OVS only
    supports Python 3 it's possible to replace pyOpenSSL with "import ssl"
    included in base Python 3.
    
    Stream recv and send had to be splitted as _recv and _send, since SSLError
    is a subclass of socket.error and so it was not possible to except for
    SSLWantReadError and SSLWantWriteError in recv and send of SSLStream.
    
    TCPstream._open cannot be used in SSLStream, since Python ssl module
    requires the SSL socket to be created before connecting it, so
    SSLStream._open needs to create the socket, create SSL socket and then
    connect the SSL socket.

- python: socket-util: Split inet_open_active function and use connect_ex. [RH git: 2e704b371c]
    In an upcoming patch, PyOpenSSL will be replaced with Python ssl module,
    but in order to do an async connection with Python ssl module the ssl
    socket must be created when the socket is created, but before the
    socket is connected.
    
    So, inet_open_active function is splitted in 3 parts:
    - inet_create_socket_active: creates the socket and returns the family and
      the socket, or (error, None) if some error needs to be returned.
    - inet_connect_active: connect the socket and returns the errno (it
      returns 0 if errno is EINPROGRESS or EWOULDBLOCK).
    
    connect is replaced by connect_ex, since Python suggest to use it for
    asynchronous connects and it's also cleaner since inet_connect_active
    returns errno that connect_ex already returns, moreover due to a Python
    limitation connect cannot not be used with ssl module.
    
    inet_open_active function is changed in order to use the new functions
    inet_create_socket_active and inet_connect_active.

    commit 317b1bfd7dd315e241c158e6d4095002ff391ee3
    Author: Ilya Maximets <i.maximets@ovn.org>
    Date:   Tue Sep 28 13:17:21 2021 +0200
    
        ovsdb: Don't let transaction history grow larger than the database.
    
        If user frequently changes a lot of rows in a database, transaction
        history could grow way larger than the database itself.  This wastes
        a lot of memory and also makes monitor_cond_since slower than
        usual monotor_cond if the transaction id is old enough, because
        re-construction of the changes from a history is slower than just
        creation of initial database snapshot.  This is also the case if
        user deleted a lot of data, so transaction history still holds all of
        it while the database itself doesn't.
    
        In case of current lb-per-service model in ovn-kubernetes, each
        load-balancer is added to every logical switch/router.  Such a
        transaction touches more than a half of a OVN_Northbound database.
        And each of these transactions is added to the transaction history.
        Since transaction history depth is 100, in worst case scenario,
        it will hold 100 copies of a database increasing memory consumption
        dramatically.  In tests with 3000 LBs and 120 LSs, memory goes up
        to 3 GB, while holding at 30 MB if transaction history disabled in
        the code.
    
        Fixing that by keeping count of the number of ovsdb_atom's in the
        database and not allowing the total number of atoms in transaction
        history to grow larger than this value.  Counting atoms is fairly
        cheap because we don't need to iterate over them, so it doesn't have
        significant performance impact.  It would be ideal to measure the
        size of individual atoms, but that will hit the performance.
        Counting cells instead of atoms is not sufficient, because OVN
        users are adding hundreds or thousands of atoms to a single cell,
        so they are largely different in size.

- ovsdb: transaction: Incremental reassessment of weak refs. [RH git: e8a363db49] (#2005958)
    commit 4dbff9f0a68579241ac1a040726be3906afb8fe9
    Author: Ilya Maximets <i.maximets@ovn.org>
    Date:   Sat Oct 16 03:20:23 2021 +0200
    
        ovsdb: transaction: Incremental reassessment of weak refs.
    
        The main idea is to not store list of weak references in the source
        row, so they all don't need to be re-checked/updated on every
        modification of that source row.  The point is that source row already
        knows UUIDs of all destination rows stored in the data, so there is no
        much profit in storing this information somewhere else.  If needed,
        destination row can be looked up and reference can be looked up in the
        destination row.  For the fast lookup, destination row now stores
        references in a hash map.
    
        Weak reference structure now contains the table and uuid of a source
        row instead of a direct pointer.  This allows to replace/update the
        source row without breaking any weak references stored in destination
        rows.
    
        Structure also now contains the key-value pair of atoms that triggered
        creation of this reference.  These atoms can be used to quickly
        subtract removed references from a source row.  During reassessment,
        ovsdb now only needs to care about new added or removed atoms, and
        atoms that got removed due to removal of the destination rows, but
        these are marked for reassessment by the destination row.
    
        ovsdb_datum_subtract() is used to remove atoms that points to removed
        or incorrect rows, so there is no need to re-sort datum in the end.
    
        Results of an OVN load-balancer benchmark that adds 3K load-balancers
        to each of 120 logical switches and 120 logical routers in the OVN
        sandbox with clustered Northbound database and then removes them:
    
        Before:
    
          %CPU  CPU Time  CMD
          86.8  00:16:05  ovsdb-server nb1.db
          44.1  00:08:11  ovsdb-server nb2.db
          43.2  00:08:00  ovsdb-server nb3.db
    
        After:
    
          %CPU  CPU Time  CMD
          54.9  00:02:58  ovsdb-server nb1.db
          33.3  00:01:48  ovsdb-server nb2.db
          32.2  00:01:44  ovsdb-server nb3.db
    
        So, on a cluster leader the processing time dropped by 5.4x, on
        followers - by 4.5x.  More load-balancers - larger the performance
        difference.  There is a slight increase of memory usage, because new
        reference structure is larger, but the difference is not significant.

- ovsdb-data: Deduplicate string atoms. [RH git: 24e7d1140e] (#2006839)
    commit 429b114c5aadee24ccfb16ad7d824f45cdcea75a
    Author: Ilya Maximets <i.maximets@ovn.org>
    Date:   Wed Sep 22 09:28:50 2021 +0200
    
        ovsdb-server spends a lot of time cloning atoms for various reasons,
        e.g. to create a diff of two rows or to clone a row to the transaction.
        All atoms, except for strings, contains a simple value that could be
        copied in efficient way, but duplicating strings every time has a
        significant performance impact.
    
        Introducing a new reference-counted structure 'ovsdb_atom_string'
        that allows to not copy strings every time, but just increase a
        reference counter.
    
        This change allows to increase transaction throughput in benchmarks
        up to 2x for standalone databases and 3x for clustered databases, i.e.
        number of transactions that ovsdb-server can handle per second.
        It also noticeably reduces memory consumption of ovsdb-server.
    
        Next step will be to consolidate this structure with json strings,
        so we will not need to duplicate strings while converting database
        objects to json and back.

- ovsdb-data: Add function to apply diff in-place. [RH git: df0e4bda98] (#2006851)
    commit 32b51326ef9c307b4acd0bacafb0218dd1372f3d
    Author: Ilya Maximets <i.maximets@ovn.org>
    Date:   Thu Sep 23 01:47:24 2021 +0200
    
        ovsdb_datum_apply_diff() is heavily used in ovsdb transactions, but
        it's linear in terms of number of comparisons.  And it also clones
        all the atoms along the way.  In most cases size of a diff is much
        smaller than the size of the original datum, this allows to perform
        the same operation in-place with only O(diff->n * log2(old->n))
        comparisons and O(old->n + diff->n) memory copies with memcpy.
        Using this function while applying diffs read from the storage gives
        a significant performance boost and allows to execute much more
        transactions per second.

- ovsdb-data: Optimize subtraction of sets. [RH git: 5bace82405] (#2005483)
    commit bb12b63176389e516ddfefce20dfa165f24430fb
    Author: Ilya Maximets <i.maximets@ovn.org>
    Date:   Thu Sep 23 01:47:23 2021 +0200
    
        Current algorithm for ovsdb_datum_subtract looks like this:
    
          for-each atom in a:
              if atom in b:
                  swap(atom, <last atom in 'a'>)
                  destroy(atom)
          quicksort(a)
    
        Complexity:
    
          Na * log2(Nb)  +  (Na - Nb) * log2(Na - Nb)
            Search          Comparisons for quicksort
    
        It's not optimal, especially because Nb << Na in a vast majority of
        cases.
    
        Reversing the search phase to look up atoms from 'b' in 'a', and
        closing gaps from deleted elements in 'a' by plain memory copy to
        avoid quicksort.
    
        Resulted complexity:
    
          Nb * log2(Na)  +    (Na - Nb)
            Search          Memory copies
    
        Subtraction is heavily used while executing database transactions.
        For example, to remove one port from a logical switch in OVN.
        Complexity of such operation if original logical switch had 100 ports
        goes down from
    
         100 * log2(1)   = 100 comparisons for search and
          99 * log2(99)  = 656 comparisons for quicksort
                           ------------------------------
                           756 comparisons in total
        to only
    
           1 * log2(100) = 7 comparisons for search
           + memory copy of 99 * sizeof (union ovsdb_atom) bytes.
    
        We could use memmove to close the gaps after removing atoms, but
        it will lead to 2 memory copies inside the call, while we can perform
        only one to the temporary 'result' and swap pointers.
    
        Performance in cases, where sizes of 'a' and 'b' are comparable,
        should not change.  Cases with Nb >> Na should not happen in practice.
    
        All in all, this change allows ovsdb-server to perform several times
        more transactions, that removes elements from sets, per second.

- ovsdb-data: Optimize union of sets. [RH git: e2a4c7d794] (#2005483)
    commit 51946d22274cd591dc061358fb507056fbd91420
    Author: Ilya Maximets <i.maximets@ovn.org>
    Date:   Thu Sep 23 01:47:22 2021 +0200
    
        Current algorithm of ovsdb_datum_union looks like this:
    
          for-each atom in b:
              if not bin_search(a, atom):
                  push(a, clone(atom))
          quicksort(a)
    
        So, the complexity looks like this:
    
           Nb * log2(Na)   +    Nb     +   (Na + Nb) * log2(Na + Nb)
           Comparisons        clones       Comparisons for quicksort
           for search
    
        ovsdb_datum_union() is heavily used in database transactions while
        new element is added to a set.  For example, if new logical switch
        port is added to a logical switch in OVN.  This is a very common
        use case where CMS adds one new port to an existing switch that
        already has, let's say, 100 ports.  For this case ovsdb-server will
        have to perform:
    
           1 * log2(100)  + 1 clone + 101 * log2(101)
           Comparisons                Comparisons for
           for search                   quicksort.
               ~7           1            ~707
           Roughly 714 comparisons of atoms and 1 clone.
    
        Since binary search can give us position, where new atom should go
        (it's the 'low' index after the search completion) for free, the
        logic can be re-worked like this:
    
          copied = 0
          for-each atom in b:
              desired_position = bin_search(a, atom)
              push(result, a[ copied : desired_position - 1 ])
              copied = desired_position
              push(result, clone(atom))
          push(result, a[ copied : Na ])
          swap(a, result)
    
        Complexity of this schema:
    
           Nb * log2(Na)   +    Nb     +         Na
           Comparisons        clones       memory copy on push
           for search
    
        'swap' is just a swap of a few pointers.  'push' is not a 'clone',
        but a simple memory copy of 'union ovsdb_atom'.
    
        In general, this schema substitutes complexity of a quicksort
        with complexity of a memory copy of Na atom structures, where we're
        not even copying strings that these atoms are pointing to.
    
        Complexity in the example above goes down from 714 comparisons
        to 7 comparisons and memcpy of 100 * sizeof (union ovsdb_atom) bytes.
    
        General complexity of a memory copy should always be lower than
        complexity of a quicksort, especially because these copies usually
        performed in bulk, so this new schema should work faster for any input.
    
        All in all, this change allows to execute several times more
        transactions per second for transactions that adds new entries to sets.
    
        Alternatively, union can be implemented as a linear merge of two
        sorted arrays, but this will result in O(Na) comparisons, which
        is more than Nb * log2(Na) in common case, since Na is usually
        far bigger than Nb.  Linear merge will also mean per-atom memory
        copies instead of copying in bulk.
    
        'replace' functionality of ovsdb_datum_union() had no users, so it
        just removed.  But it can easily be added back if needed in the future.

- ovsdb: transaction: Use diffs for strong reference counting. [RH git: 85da133eaa] (#2003203)
    commit b2712d026eae2d9a5150c2805310eaf506e1f162
    Author: Ilya Maximets <i.maximets@ovn.org>
    Date:   Tue Sep 14 00:19:57 2021 +0200
    
        Currently, even if one reference added to the set of strong references
        or removed from it, ovsdb-server will walk through the whole set and
        re-count references to other rows.  These referenced rows will also be
        added to the transaction in order to re-count their references.
    
        For example, every time Logical Switch Port added to a Logical Switch,
        OVN Northbound database server will walk through all ports of this
        Logical Switch, clone their rows, and re-count references.  This is
        not very efficient.  Instead, it can only increase reference counters
        for added references and reduce for removed ones.  In many cases this
        will be only one row affected in the Logical_Switch_Port table.
    
        Introducing new function that generates a diff of two datum objects,
        but stores added and removed atoms separately, so they can be used
        to increase or decrease row reference counters accordingly.
    
        This change allows to perform several times more transactions that
        adds or removes strong references to/from sets per second, because
        ovsdb-server no longer clones and re-counts rows that are irrelevant
        to current transaction.

- ovsdb: monitor: Store serialized json in a json cache. [RH git: bc20330c85] (#1996152)
    commit 43e66fc27659af2a5c976bdd27fe747b442b5554
    Author: Ilya Maximets <i.maximets@ovn.org>
    Date:   Tue Aug 24 21:00:39 2021 +0200
    
        Same json from a json cache is typically sent to all the clients,
        e.g., in case of OVN deployment with ovn-monitor-all=true.
    
        There could be hundreds or thousands connected clients and ovsdb
        will serialize the same json object for each of them before sending.
    
        Serializing it once before storing into json cache to speed up
        processing.
    
        This change allows to save a lot of CPU cycles and a bit of memory
        since we need to store in memory only a string and not the full json
        object.
    
        Testing with ovn-heater on 120 nodes using density-heavy scenario
        shows reduction of the total CPU time used by Southbound DB processes
        from 256 minutes to 147.  Duration of unreasonably long poll intervals
        also reduced dramatically from 7 to 2 seconds:
    
                   Count   Min    Max   Median    Mean   95 percentile

- raft: Don't keep full json objects in memory if no longer needed. [RH git: 4606423e8b] (#1990058)
    commit 0de882954032aa37dc943bafd72c33324aa0c95a
    Author: Ilya Maximets <i.maximets@ovn.org>
    Date:   Tue Aug 24 21:00:38 2021 +0200
    
        raft: Don't keep full json objects in memory if no longer needed.
    
        Raft log entries (and raft database snapshot) contains json objects
        of the data.  Follower receives append requests with data that gets
        parsed and added to the raft log.  Leader receives execution requests,
        parses data out of them and adds to the log.  In both cases, later
        ovsdb-server reads the log with ovsdb_storage_read(), constructs
        transaction and updates the database.  On followers these json objects
        in common case are never used again.  Leader may use them to send
        append requests or snapshot installation requests to followers.
        However, all these operations (except for ovsdb_storage_read()) are
        just serializing the json in order to send it over the network.
    
        Json objects are significantly larger than their serialized string
        representation.  For example, the snapshot of the database from one of
        the ovn-heater scale tests takes 270 MB as a string, but 1.6 GB as
        a json object from the total 3.8 GB consumed by ovsdb-server process.
    
        ovsdb_storage_read() for a given raft entry happens only once in a
        lifetime, so after this call, we can serialize the json object, store
        the string representation and free the actual json object that ovsdb
        will never need again.  This can save a lot of memory and can also
        save serialization time, because each raft entry for append requests
        and snapshot installation requests serialized only once instead of
        doing that every time such request needs to be sent.
    
        JSON_SERIALIZED_OBJECT can be used in order to seamlessly integrate
        pre-serialized data into raft_header and similar json objects.
    
        One major special case is creation of a database snapshot.
        Snapshot installation request received over the network will be parsed
        and read by ovsdb-server just like any other raft log entry.  However,
        snapshots created locally with raft_store_snapshot() will never be
        read back, because they reflect the current state of the database,
        hence already applied.  For this case we can free the json object
        right after writing snapshot on disk.
    
        Tests performed with ovn-heater on 60 node density-light scenario,
        where on-disk database goes up to 97 MB, shows average memory
        consumption of ovsdb-server Southbound DB processes decreased by 58%
        (from 602 MB to 256 MB per process) and peak memory consumption
        decreased by 40% (from 1288 MB to 771 MB).
    
        Test with 120 nodes on density-heavy scenario with 270 MB on-disk
        database shows 1.5 GB memory consumption decrease as expected.
        Also, total CPU time consumed by the Southbound DB process reduced
        from 296 to 256 minutes.  Number of unreasonably long poll intervals
        reduced from 2896 down to 1934.
    
        Deserialization is also implemented just in case.  I didn't see this
        function being invoked in practice.

- json: Add support for partially serialized json objects. [RH git: 885e5ce1b5] (#1990058)
    commit b0bca6f27aae845c3ca8b48d66a7dbd3d978162a
    Author: Ilya Maximets <i.maximets@ovn.org>
    Date:   Tue Aug 24 21:00:37 2021 +0200
    
        json: Add support for partially serialized json objects.
    
        Introducing a new json type JSON_SERIALIZED_OBJECT.  It's not an
        actual type that can be seen in a json message on a wire, but
        internal type that is intended to hold a serialized version of
        some other json object.  For this reason it's defined after the
        JSON_N_TYPES to not confuse parsers and other parts of the code
        that relies on compliance with RFC 4627.
    
        With this JSON type internal users may construct large JSON objects,
        parts of which are already serialized.  This way, while serializing
        the larger object, data from JSON_SERIALIZED_OBJECT can be added
        directly to the result, without additional processing.
    
        This will be used by next commits to add pre-serialized JSON data
        to the raft_header structure, that can be converted to a JSON
        before writing the file transaction on disk or sending to other
        servers.  Same technique can also be used to pre-serialize json_cache
        for ovsdb monitors, this should allow to not perform serialization
        for every client and will save some more memory.
    
        Since serialized JSON is just a string, reusing the 'json->string'
        pointer for it.

- json: Optimize string serialization. [RH git: bb1654da63] (#1990069)
    commit 748010ff304b7cd2c43f4eb98a554433f0df07f9
    Author: Ilya Maximets <i.maximets@ovn.org>
    Date:   Tue Aug 24 23:07:22 2021 +0200
    
        json: Optimize string serialization.
    
        Current string serialization code puts all characters one by one.
        This is slow because dynamic string needs to perform length checks
        on every ds_put_char() and it's also doesn't allow compiler to use
        better memory copy operations, i.e. doesn't allow copying few bytes
        at once.
    
        Special symbols are rare in a typical database.  Quotes are frequent,
        but not too frequent.  In databases created by ovn-kubernetes, for
        example, usually there are at least 10 to 50 chars between quotes.
        So, it's better to count characters that doesn't require escaping
        and use fast data copy for the whole sequential block.
    
        Testing with a synthetic benchmark (included) on my laptop shows
        following performance improvement:
    
           Size      Q  S       Before       After       Diff
         -----------------------------------------------------
         100000      0  0 :    0.227 ms     0.142 ms   -37.4 %
         100000      2  1 :    0.277 ms     0.186 ms   -32.8 %
         100000      10 1 :    0.361 ms     0.309 ms   -14.4 %
         10000000    0  0 :   22.720 ms    12.160 ms   -46.4 %
         10000000    2  1 :   27.470 ms    19.300 ms   -29.7 %
         10000000    10 1 :   37.950 ms    31.250 ms   -17.6 %
         100000000   0  0 :  239.600 ms   126.700 ms   -47.1 %
         100000000   2  1 :  292.400 ms   188.600 ms   -35.4 %
         100000000   10 1 :  387.700 ms   321.200 ms   -17.1 %
    
        Here Q - probability (%) for a character to be a '\"' and
        S - probability (%) to be a special character ( < 32).
    
        Testing with a closer to real world scenario shows overall decrease
        of the time needed for database compaction by ~5-10 %.  And this
        change also decreases CPU consumption in general, because string
        serialization is used in many different places including ovsdb
        monitors and raft.
