pg_autoctl enable secondary¶
pg_autoctl enable secondary - Enable secondary nodes on a formation
Synopsis¶
This feature makes the most sense when using the Enterprise Edition of
pg_auto_failover, which is fully compatible with Citus formations. When
secondary
are enabled, then Citus workers creation policy is to assign a
primary node then a standby node for each group. When secondary
is
disabled the Citus workers creation policy is to assign only the primary
nodes.
