My largest, ~600GB database was awful to compact. Because much of it seldom

it grows, compaction is no longer a problem. However, I appear to be
suffering now when it comes to replication.

Thanks for the info on querying replication status.
Also, can you share the logs? I would like to see the errors and stack
traces you get - without them it's hard to tell what is going wrong.
I've got a log that consists mostly of stack traces that occured over
about 8 minutes. It's 1.7M lines long, so I'll attach a snippet and
hope it's enough. Please let me know if more would be helpful.
However, 500 replications in parallel seems a bit too much.
Perhaps I shouldn't do continuous replication. Would it be better if I
had my replication daemon round-robin through the databases, replicating
one (or perhaps a few) at a time? If I change my writers to that they
write to each server, then replication won't usually have that much to do.
