gp_distributed_xacts

The gp_distributed_xacts view contains information about LightDB-A Database distributed transactions. A distributed transaction is a transaction that involves modifying data on the segment instances. LightDB-A’s distributed transaction manager ensures that the segments stay in synch. This view allows you to see the currently active sessions and their associated distributed transactions.
