Let me explain my question. One of the key aspects of logical replication is, that you can define what to replicate. That wouldn't work in this way, that's why i'm asking.
Regards, Andreas
I have streaming-replication of a cluster containing many databases to a standby-server. I need a reporting-server which only needs a subset of some (large) tables of one database and am planning to use the built-in logical replication for that. It is my understanding that logical replication will cause more wal-traffic so I'm trying to offload wal-traffic from the primary. I thought using logical replication from the standby would help with that but realized it's not supported in v10. Im I wrong in planning this way?
