Dear all,
I'd like to ask for help or advice with choosing the best replication setup for
my task.
I need to listen to continuous inserts/deletes/updates over a set of tables,
and serve them over http, so I would like to off-load this procedure to a
separate slave machine. I thought that logical master-slave replication could
be the best match here, but I couldn't find enough details in the documentation
which implementation would match my needs best.
Basically, I need to:
a) replicate selected tables to a hot standby slave
b) on the slave, listen for the insert/update/delete events (either through triggers or logical decoder plugin)
While I see that a) should be feasible, I can't see if it's possible to do b) at all.
Also, with so many replication solutions, I don't want to test them all one by one, but
rather would like to ask for help choosing the one goes best here -- and if there's none,
an alternative setup then.

Sincerely,
Dmitry Karasik
