1) restore child and parent index (order doesn't matter);
2) attach child index;

1) restore child and parent index (order doesn't matter);
2) attach child index;
3) set cluster on child and parent index (order doesn't matter);

..since it needs to be restored after any child indexes are restored *and

1) restore child and parent index (order doesn't matter);
2) attach child index;
3) set cluster on child and parent index (order doesn't matter);

1) restore child and parent index (order doesn't matter);
2) attach child index;
3) set cluster on child and parent index (order doesn't matter);

..since it needs to be restored after any child indexes are restored *and

1) restore child and parent index (order doesn't matter);
2) attach child index;
3) set cluster on child and parent index (order doesn't matter);

1) restore child and parent index (order doesn't matter);
2) attach child index;
3) set cluster on child and parent index (order doesn't matter);

1) restore child and parent index (order doesn't matter);
2) attach child index;
3) set cluster on child and parent index (order doesn't matter);

1) restore child and parent index (order doesn't matter);
2) attach child index;
3) set cluster on child and parent index (order doesn't matter);

1) restore child and parent index (order doesn't matter);
2) attach child index;
3) set cluster on child and parent index (order doesn't matter);

..since it needs to be restored after any child indexes are restored *and

2) attach child index;
3) set cluster on child and parent index (order doesn't matter);

1) restore child and parent index (order doesn't matter);
2) attach child index;
3) set cluster on child and parent index (order doesn't matter);

..since it needs to be restored after any child indexes are restored *and
attached*. The order needs to be:
1) restore child and parent index (order doesn't matter);
2) attach child index;
3) set cluster on child and parent index (order doesn't matter);

* Re: High CPU consumption in cascade replication with large number of walsenders and ConditionVariable broadcast issues
@ 2025-04-22 12:40 Alexey Makhmutov <[email protected]>
0 siblings, 0 replies; 94+ messages in thread
From: Alexey Makhmutov @ 2025-04-22 12:40 UTC (permalink / raw)
To: pgsql-hackers
After playing with the patch a little more, we’ve come to the
conclusion, that the idea to signal CV broadcast from the timer handler
is a risky one, as it creates a large number of execution paths, which
are not present in current code base. It's hard to prove correctness of
application behavior in each such case, so we've decided to use a
different approach.
In the new version of the patch we use timer handler only to set the
flag, which is then checked in the ProcessStartupProcInterrupts
function. This allow us to send signal on timeout if the startup process
is waiting for the arrival of new WAL records (in ReadRecord), but the
notification may be delayed while record is being applied (during redo
handler invocation from ApplyWalRecord). This could increase delay for
some corner cases with non-trivial WAL records like ‘drop database’, but
this should be a rare case and walsender process have its own limit on
the wait time, so the delay won’t be indefinite even in this case.
A new variant of the patch is attached in case anybody else wants to
play with this patch and approach. A slightly improved test case and
formatted CV patch (which is not strictly required anymore for this
case) are attached as well.
Thanks,
Alexey

Subject: [PATCH 1/2] Ensure that content of the wait list on CV is aligned
with cv_sleep_target value
Wait on the ConditionVariable could be interleaved with interruption handlers,
such as timers. If such handler uses CV calls (i.e. ConditionVariableBroadcast),
then value of the cv_sleep_target could be null or point to a different CV after
wakeup. In this case we should not try to add ourselves to the wakeup wait list,
as subsequent call to ConditionVariableCancelSleep won't be able to find our CV
to clear its list. We should instead return control to the client, so the exit
condition for the CV external wait loop could be checked. If wait is still
required, then next invocation of ConditionVariableTimedSleep will perform the
required setup procedures for CV. Behavior before this change results in the
mismatch between cv_sleep_target value and content of the wakeup list, so the
next invocation of ConditionVariableBroadcast method may fail due to presence of
current process in the list.

Subject: [PATCH 2/2] Implement batching for WAL records notification during
cascade replication
Currently standby server notifies walsenders after applying of each WAL
record during cascade replication. This creates a bottleneck in case of large
number of sender processes during WalSndWakeup invocation. This change
introduces batching for such notifications, which are now sent either after
certain number of applied records or specified time interval (whichever comes
first).
