For example 'ports' column of the 'Logical_Switch' +table could contain thousands of ports in a set. + +Current strategy of nbctl while adding a new port to the set is to +copy all existing ports, add one and set the new set of ports. +Similar behavior is for deletion too. + +If we have 1000 ports and want to add one more, resulted transaction +in current code will look like this: + + {transact, + < wait operation > + < create new lsp in Logical_Switch_Port table > + + where: _uuid == 'logical switch row uuid' + op : update + rows : ports ['< list of current 1000 ports + 1 new >'] + } + +The code was written before support for partial updates for sets was +implemented. Now we have it and can replace the old strategy. +With this change resulted transaction will be: + + {transact, + < wait operation > + < create new lsp in Logical_Switch_Port table > + + where: _uuid == 'logical switch row uuid' + op : mutate + mutations : ports insert ['< 1 uuid of a new lsp >'] + } + +Unfortunately, for now, this only decreases transaction size in half, +because '', that is still in the transaction, contains +the full current list of ports: + + where: _uuid == 'logical switch row uuid' + op : wait + until: == + rows : ports ['< list of current 1000 ports >'] + +But anyway, beside the overall code cleanup, this reduces transaction +size in half and should reduce pressure on the ovsdb-server since it +will not need to parse and process all 1000 ports twice. + +This change doesn't affect 'append_request' messages within the raft +cluster, because ovsdb-server is not smart enough to use mutations +there, and this will also not affect 'update' messages from the +ovsdb-server to its clients, because it is smart enough to construct +'modify' updates regardless of the original transaction. + +One difference between full updates and partial is that partial +changes are not visible for the idl client until transaction is +committed and the update received from the server. New switch ports +are not visible while iterating over 'ports' of the logical switch and +removed ports are still there. For this reason, we have to maintain +runtime cache of the mapping between ports and routers/switches they +attached to. + +Acked-by: Mark Michelson +Signed-off-by: Ilya Maximets +Signed-off-by: Numan Siddique +--- + utilities/ovn-nbctl.c | 350 +++++++++++------------------------------- + 1 file changed, 87 insertions(+), 263 deletions(-) + +diff --git a/utilities/ovn-nbctl.c b/utilities/ovn-nbctl.c +index cbf2cb1f1..7c4dce12a 100644 +--- a/utilities/ovn-nbctl.c ++++ b/utilities/ovn-nbctl.c +@@ -126,7 +126,11 @@ static char * OVS_WARN_UNUSED_RESULT main_loop(const char *args, + static void server_loop(struct ovsdb_idl *idl, int argc, char *argv[]); + + /* A context for keeping track of which switch/router certain ports are +- * connected to. */ ++ * connected to. ++ * ++ * It is required to track changes that we did within current set of commands ++ * because partial updates of sets in database are not reflected in the idl ++ * until transaction is committed and updates received from the server. */ + struct nbctl_context { + struct ctl_context base; + struct shash lsp_to_ls_map; +@@ -1508,21 +1512,15 @@ nbctl_lsp_add(struct ctl_context *ctx) + + /* Insert the logical port into the logical switch. */ + nbrec_logical_switch_verify_ports(ls); +- struct nbrec_logical_switch_port **new_ports = xmalloc(sizeof *new_ports * +- (ls->n_ports + 1)); +- nullable_memcpy(new_ports, ls->ports, sizeof *new_ports * ls->n_ports); +- new_ports[ls->n_ports] = CONST_CAST(struct nbrec_logical_switch_port *, +- lsp); +- nbrec_logical_switch_set_ports(ls, new_ports, ls->n_ports + 1); +- free(new_ports); ++ nbrec_logical_switch_update_ports_addvalue(ls, lsp); + + /* Updating runtime cache. */ + shash_add(&nbctx->lsp_to_ls_map, lsp_name, ls); + } + +-/* Removes logical switch port 'ls->ports[idx]'. */ ++/* Removes logical switch port 'lsp' from the logical switch 'ls'. */ + static void +-remove_lsp(struct ctl_context *ctx, size_t idx, ++remove_lsp(struct ctl_context *ctx, + const struct nbrec_logical_switch *ls, + const struct nbrec_logical_switch_port *lsp) + { +@@ -1534,12 +1532,8 @@ remove_lsp(struct ctl_context *ctx, size_t idx, + /* First remove 'lsp' from the array of ports.
