13.8. bdr.bdr_global_locks

bdr.bdr_global_locks is an implementation detail for BDR's global DDL locking mechanism. See DDL replication and Monitoring. Do not modify this table directly.

Note that a state of acquired only indicates successful acquisition of the lock on this node; other nodes may still be trying to acquire their local DDL lock in response to a global DDL lock request, so it might not be granted yet. Details on how this table works can be found in the comments at the start of the source file bdr_locks.c.

See Section 8.1.1 for more detail on how the global DDL lock works.
