Hi, hackers!
*** The problem ***
I'm investigating some cases of reduced database performance due to MultiXactOffsetLock contention (80% MultiXactOffsetLock, 20% IO DataFileRead).
The problem manifested itself during index repack and constraint validation. Both being effectively full table scans.
The database workload contains a lot of select for share\select for update queries. I've tried to construct synthetic world generator and could not achieve similar lock configuration: I see a lot of different locks in wait events, particularly a lot more MultiXactMemberLocks. But from my experiments with synthetic workload, contention of MultiXactOffsetLock can be reduced by increasing NUM_MXACTOFFSET_BUFFERS=8 to bigger numbers.
*** Question 1 ***
Is it safe to increase number of buffers of MultiXact\All SLRUs, recompile and run database as usual?
I cannot experiment much with production. But I'm mostly sure that bigger buffers will solve the problem.
*** Question 2 ***
Probably, we could do GUCs for SLRU sizes? Are there any reasons not to do them configurable? I think multis, clog, subtransactions and others will benefit from bigger buffer. But, probably, too much of knobs can be confusing.
*** Question 3 ***
MultiXact offset lock is always taken as exclusive lock. It turns MultiXact Offset subsystem to single threaded. If someone have good idea how to make it more concurrency-friendly, I'm willing to put some efforts into this.
Probably, I could just add LWlocks for each offset buffer page. Is it something worth doing? Or are there any hidden cavers and difficulties?
Thanks!
Best regards, Andrey Borodin.

I've created benchmark[0] imitating MultiXact pressure on my laptop: 7 clients are concurrently running select "select * from table where primary_key = ANY ($1) for share" where $1 is array of identifiers so that each tuple in a table is locked by different set of XIDs. During this benchmark I observe contention of MultiXactControlLock in pg_stat_activity

pid | wait_event | wait_event_type | state | query
-------+----------------------------+-----------------+--------+----------------------------------------------------

41375 | MultiXactOffsetControlLock | LWLock | active | select * from t1 where i = ANY ($1) for share
41377 | MultiXactOffsetControlLock | LWLock | active | select * from t1 where i = ANY ($1) for share
41378 | | | active | select * from t1 where i = ANY ($1) for share

41381 | | | active | select * from t1 where i = ANY ($1) for share
41383 | MultiXactOffsetControlLock | LWLock | active | select * from t1 where i = ANY ($1) for share
41385 | MultiXactOffsetControlLock | LWLock | active | select * from t1 where i = ANY ($1) for share
(8 rows)
Finally, the benchmark is measuring time to execute select for update 42 times.
I've went ahead and created 3 patches:
1. Configurable SLRU buffer sizes for MultiXacOffsets and MultiXactMembers
2. Reduce locking level to shared on read of MultiXactId members
3. Configurable cache size
I've found out that:
1. When MultiXact working set does not fit into buffers - benchmark results grow very high. Yet, very big buffers slow down benchmark too. For this benchmark optimal SLRU size id 32 pages for offsets and 64 pages for members (defaults are 8 and 16 respectively).
2. Lock optimisation increases performance by 5% on default SLRU sizes. Actually, benchmark does not explicitly read MultiXactId members, but when it replaces one with another - it have to read previous set. I understand that we can construct benchmark to demonstrate dominance of any algorithm and 5% of synthetic workload is not a very big number. But it just make sense to try to take shared lock for reading.
3. Manipulations with cache size do not affect benchmark anyhow. It's somewhat expected: benchmark is designed to defeat cache, either way OffsetControlLock would not be stressed.
For our workload, I think we will just increase numbers of SLRU sizes. But patchset may be useful for tuning and as a performance optimisation of MultiXact.
Also MultiXacts seems to be not very good fit into SLRU design. I think it would be better to use B-tree as a container. Or at least make MultiXact members extendable in-place (reserve some size when multixact is created).
When we want to extend number of locks for a tuple currently we will:
1. Iterate through all SLRU buffers for offsets to read current offset (with exclusive lock for offsets)
2. Iterate through all buffers for members to find current members (with exclusive lock for members)
3. Create new members array with +1 xid
4. Iterate through all cache members to find out maybe there are any such cache item as what we are going to create
5. iterate over 1 again for write
6. Iterate over 2 again for write
Obviously this does not scale well - we cannot increase SLRU sizes for too long.
Thanks! I'd be happy to hear any feedback.
Best regards, Andrey Borodin.

Subject: [PATCH v1 2/3] Use shared lock in GetMultiXactIdMembers for offsets
and members
Previously read of multixact required exclusive control locks in
offstes and members SLRUs. This could lead to contention.
In this commit we take advantge of SimpleLruReadPage_ReadOnly
similar to CLOG usage.

I'm looking more at MultiXact and it seems to me that we have a race condition there.
When we create a new MultiXact we do:
1. Generate new MultiXactId under MultiXactGenLock
2. Record new mxid with members and offset to WAL
3. Write offset to SLRU under MultiXactOffsetControlLock
4. Write members to SLRU under MultiXactMemberControlLock
When we read MultiXact we do:
1. Retrieve offset by mxid from SLRU under MultiXactOffsetControlLock
2. If offset is 0 - it's not filled in at step 4 of previous algorithm, we sleep and goto 1
3. Retrieve members from SLRU under MultiXactMemberControlLock
4. ..... what we do if there are just zeroes because step 4 is not executed yet? Nothing, return empty members list.
What am I missing?
Best regards, Andrey Borodin.

But, don't we hold exclusive lock on the buffer through all the steps
above?

So transactions never see such incomplete mxids, I believe.

Yes...Unless MultiXact is observed on StandBy. This could lead to observing inconsistent snapshot: one of lockers committed tuple delete, but standby sees it as alive.

I've observed sleep in step 2. I believe it's possible to observe special effects of step 4 too.
Maybe we could add lock on standby to dismiss this 1000us wait? Sometimes it hits hard on Standbys: if someone is locking whole table on primary - all seq scans on standbys follow him with MultiXactOffsetControlLock contention.

Ah, right. I looked from GetNewMultiXactId. Actually
XLOG_MULTIXACT_CREATE_ID is not protected from concurrent reference to
the creating mxact id. And GetMultiXactIdMembers is considering that
case.

GetMultiXactIdMembers believes that 4 is successfully done if 2
returned valid offset, but actually that is not obvious.
If we add a single giant lock just to isolate ,say,
GetMultiXactIdMember and RecordNewMultiXact, it reduces concurrency
unnecessarily. Perhaps we need finer-grained locking-key for standby
that works similary to buffer lock on primary, that doesn't cause
confilicts between irrelevant mxids.

We can just replay members before offsets. If offset is already there - members are there too.
But I'd be happy if we could mitigate those 1000us too - with a hint about last maixd state in a shared MX state, for example.
Actually, if we read empty mxid array instead of something that is replayed just yet - it's not a problem of inconsistency, because transaction in this mxid could not commit before we started. ISTM.
So instead of fix, we, probably, can just add a comment. If this reasoning is correct.

Generally in such cases, condition variables would work. In the
attached PoC, the reader side gets no penalty in the "likely" code
path. The writer side always calls ConditionVariableBroadcast but the

The step 4 of the reader side reads the members of the target mxid. It
is already written if the offset of the *next* mxid is filled-in.

Thanks! That really looks like a good solution without magic timeouts. Beautiful!
I think I can create temporary extension which calls MultiXact API and tests edge-cases like this 1000us wait.
This extension will also be also useful for me to assess impact of bigger buffers, reduced read locking (as in my 2nd patch) and other tweaks.

Most often - yes, but members are not guaranteed to be filled in order. Those who win MXMemberControlLock will write first.
But nobody can read members of MXID before it is returned. And its members will be written before returning MXID.
Best regards, Andrey Borodin.

Happy to hear that, It would need to use timeout just in case, though.

Yeah, right. Otherwise assertion failure happens.

INSTR_TIME_SET_SECONDS() is useful to calculate the end of a time-bound loop
without having to convert into time units (which is
costly). INSTR_TIME_IS_LT() can be used to check the loop condition.

INSTR_TIME_SET_SECONDS() is useful to calculate the end of a time-bound loop
without having to convert into time units (which is
costly). INSTR_TIME_IS_LT() can be used to check the loop condition.

INSTR_TIME_SET_SECONDS() is useful to calculate the end of a time-bound loop
without having to convert into time units (which is
costly). INSTR_TIME_IS_LT() can be used to check the loop condition.

INSTR_TIME_SET_SECONDS() is useful to calculate the end of a time-bound loop
without having to convert into time units (which is
costly). INSTR_TIME_IS_LT() can be used to check the loop condition.

INSTR_TIME_SET_SECONDS() is useful to calculate the end of a time-bound loop
without having to convert into time units (which is
costly). INSTR_TIME_IS_LT() can be used to check the loop condition.

INSTR_TIME_SET_SECONDS() is useful to calculate the end of a time-bound loop
without having to convert into time units (which is
costly). INSTR_TIME_IS_LT() can be used to check the loop condition.

INSTR_TIME_SET_SECONDS() is useful to calculate the end of a time-bound loop
without having to convert into time units (which is
costly). INSTR_TIME_IS_LT() can be used to check the loop condition.

INSTR_TIME_SET_SECONDS() is useful to calculate the end of a time-bound loop
without having to convert into time units (which is
costly). INSTR_TIME_IS_LT() can be used to check the loop condition.

INSTR_TIME_SET_SECONDS() is useful to calculate the end of a time-bound loop
without having to convert into time units (which is
costly). INSTR_TIME_IS_LT() can be used to check the loop condition.

INSTR_TIME_SET_SECONDS() is useful to calculate the end of a time-bound loop
without having to convert into time units (which is
costly). INSTR_TIME_IS_LT() can be used to check the loop condition.

INSTR_TIME_SET_SECONDS() is useful to calculate the end of a time-bound loop
without having to convert into time units (which is
costly). INSTR_TIME_IS_LT() can be used to check the loop condition.

INSTR_TIME_SET_SECONDS() is useful to calculate the end of a time-bound loop
without having to convert into time units (which is
costly). INSTR_TIME_IS_LT() can be used to check the loop condition.

INSTR_TIME_SET_SECONDS() is useful to calculate the end of a time-bound loop
without having to convert into time units (which is
costly). INSTR_TIME_IS_LT() can be used to check the loop condition.

INSTR_TIME_SET_SECONDS() is useful to calculate the end of a time-bound loop
without having to convert into time units (which is
costly). INSTR_TIME_IS_LT() can be used to check the loop condition.

INSTR_TIME_SET_SECONDS() is useful to calculate the end of a time-bound loop
without having to convert into time units (which is
costly). INSTR_TIME_IS_LT() can be used to check the loop condition.

INSTR_TIME_SET_SECONDS() is useful to calculate the end of a time-bound loop
without having to convert into time units (which is
costly). INSTR_TIME_IS_LT() can be used to check the loop condition.

INSTR_TIME_SET_SECONDS() is useful to calculate the end of a time-bound loop
without having to convert into time units (which is
costly). INSTR_TIME_IS_LT() can be used to check the loop condition.

INSTR_TIME_SET_SECONDS() is useful to calculate the end of a time-bound loop
without having to convert into time units (which is
costly). INSTR_TIME_IS_LT() can be used to check the loop condition.

INSTR_TIME_SET_SECONDS() is useful to calculate the end of a time-bound loop
without having to convert into time units (which is
costly). INSTR_TIME_IS_LT() can be used to check the loop condition.

INSTR_TIME_SET_SECONDS() is useful to calculate the end of a time-bound loop
without having to convert into time units (which is
costly). INSTR_TIME_IS_LT() can be used to check the loop condition.

INSTR_TIME_SET_SECONDS() is useful to calculate the end of a time-bound loop
without having to convert into time units (which is
costly). INSTR_TIME_IS_LT() can be used to check the loop condition.

INSTR_TIME_SET_SECONDS() is useful to calculate the end of a time-bound loop
without having to convert into time units (which is
costly). INSTR_TIME_IS_LT() can be used to check the loop condition.

* [PATCH v9 1/2] instr_time: Add INSTR_TIME_SET_SECONDS(), INSTR_TIME_IS_LT()

INSTR_TIME_SET_SECONDS() is useful to calculate the end of a time-bound loop
without having to convert into time units (which is
costly). INSTR_TIME_IS_LT() can be used to check the loop condition.
