From f00d19593c36b20af37c4ac429ea8130d0418ed6 Mon Sep 17 00:00:00 2001 From: Peter Smith Date: Sun, 21 Feb 2021 08:12:27 +1100 Subject: [PATCH v1] Tablesync early exit. Give the tablesync worker an opportunity to see if it can exit immediately (because it has already caught-up) without it needing to process a message first before discovering that. --- src/backend/replication/logical/worker.c | 10 ++++++++++ 1 file changed, 10 insertions(+) diff --git a/src/backend/replication/logical/worker.c b/src/backend/replication/logical/worker.c index 6146b77..9abeb9c 100644 --- a/src/backend/replication/logical/worker.c +++ b/src/backend/replication/logical/worker.c @@ -2407,6 +2407,16 @@ LogicalRepApplyLoop(XLogRecPtr last_received) bool ping_sent = false; TimeLineID tli; + if (am_tablesync_worker()) + { + /* + * Give the tablesync worker an opportunity see if it can immediately + * exit, instead of handling a message (which the apply worker could + * handle) before discovering that. + */ + process_syncing_tables(last_received); + } + /* * Init the ApplyMessageContext which we clean up after each replication * protocol message. -- 1.8.3.1
