Hi all,

Based on the docs and look at the processes, it seems 1 wal sender on each
node per group.

If there is scenario of consolidating many databases (say hundreds) into 1
database (in this central cluster there are hundreds wal sender), what is
the limit number of groups?

I wonder if anyone has runs such the scenario?
