Hi

Logical slot lag 330GB on source grows faster during the huge modifications
but it should be minimized which is not happened when load goes down.

What is the action need to take for minimizing the lag to normal state.
Source version 16
Target version 16
Sufficient resources allocated and tuned replication related parameters

Regards
Durga Mahesh
