Subject: performance impact on read replicas during heavy vacuums on primary
Date: Tue, 3 Feb 2026 02:02:52 +0100
Message-ID: <[email protected]> (raw)
Is there a scenario, where a very heavy vacuum on the primary side is
affecting significantly
the read replica(s) in matter of performance (not the overall apply lag,
which is expected) of
selects? I do not get this reproduced ...only the lag is clear but even
hammering down the
primary with vaccum keeps my standby answering fine.
Cheers
