Defines the maximum amount of memory used to cache unused DSQL compiled statements.A value of zero (‘0’) means no statement caching is used.Default value is 2 megabytes.

Configures a timeout (in seconds) that is applied to the ON DISCONNECT trigger execution.The trigger will be automatically cancelled by the engine after the specified time has passed.A value of zero (‘0’) means no timeout is set.Default value is 180 seconds.

Specifies the default profiler plugin used to profile connections using the RDB$PROFILER package.

Defines whether queries should be optimized to retrieve the first records as soon as possible rather than returning the whole dataset as soon as possible.By default, retrieval of all rows is implied by the optimizer.

See also [rnfb50-dml-select-optimize] and [rnfb50-msql-optimize-set].

Defines whether OUTER joins can be converted into INNER joins by the optimizer, provided that such a transformation is possible from the query result perspective.

Enabled by default.Can be disabled to simplify the migration path if OUTER joins are used intentionally in SQL queries (e.g. as optimizer hints) even if they are known to be semantically equivalent to INNER joins.

Defines whether IN/ANY/EXISTS sub-queries can be unnested and merged with the outer query using the semi-join algorithm, provided that such a transformation is possible.

Specifies whether changes applied to the replica database will be also subject of further replication (if any configured).Default value is false (cascading is disabled).

Configuration file macros are now also supported in replication.conf.

This parameter was removed along with the removal of WNET (aka named pipes) protocol support for Windows.

This parameter was removed because Microsoft discourages using the SIO_LOOPBACK_FAST_PATH socket option.
