[Bug]: Upgrade to tsdb 2.15.1 caused selects by partitioned column to return only data after upgrade #6976

gugu · 2024-05-30T12:15:22Z

What type of bug is this?

Incorrect result

What subsystems and features are affected?

Query planner

What happened?

After upgrade timescaledb 2.14 => 2.15.1 it recreated chunks for partitioned table and does not use old chunks if I run a query with filter by partitioned column.

Example:

explain select * from clicks; -- or explain select * from clicks where path="abc123" or any other column except of host

How can we reproduce the bug?

1. Create table with partitioning by hash and date on tsdb 2.14
2. insert some data
3. upgrade to tsdb 2.15

I'm not sure it will work 100%, but I can provide any additional data from my configuration

If I try to trick optimizer it works, but does not use index in compressed rows

Hi there,

Do you get different query results using your workaround and without it? Just asking because its not clear that you are just by looking at query plans.

Space partitioning on host should in theory reduce the amount of chunks you need to query based on the partitioning column filter (host in your case).

Can you confirm this?

Thanks!

gugu · 2024-06-03T07:32:35Z

Yes. Query without workaround returns only data after the timescale upgrade happened. The query without workaround returns all matched data

antekresic · 2024-06-03T09:05:08Z

Hi again,

I've tried reproducing the issue with the data you have provided but had no luck.

Would you mind sharing the contents of your dimension, dimension_slice and chunk_constraint catalog tables? It would go a long way into debugging this issue.

You can get those like this:

SELECT * FROM _timescaledb_catalog.dimension;
SELECT * FROM _timescaledb_catalog.dimension_slice;
SELECT * FROM _timescaledb_catalog.chunk_constraint;

Thanks!

One question here: did you update from 2.14.x to 2.15.1 directly or did you first update to 2.15.0?

We had an issue with one of the update scripts for 2.15.0 which might be the culprit here.

gugu · 2024-06-04T08:06:03Z

2.15.1 directly

…

Looks like you have hit a catalog corruption bug in the upgrade process. There is a PR out to fix it but we need to also restore the catalog for your instance in order to get the database in a working order.

I'm working on a script to fix the problem and will post it here once it's done.

Question: can you run it as a superuser on your environment? That will probably be necessary in order to fix the catalog.

gugu · 2024-06-05T12:08:37Z

Yes, I have superuser access

antekresic · 2024-06-06T10:28:47Z

OK, so I have a couple of queries I would like you to run before we attempt fixing the catalog.

This one will show all the chunks that are broken:

WITH dimension_count as (                                                                                      
SELECT ht.id, count(*)
FROM _timescaledb_catalog.hypertable ht
INNER JOIN _timescaledb_catalog.dimension d
        ON d.hypertable_id = ht.id
WHERE table_name = 'clicks'
GROUP BY 1),
chunk_constraint_count AS (
SELECT c.hypertable_id, cc.chunk_id, c.schema_name, c.table_name, count(*)
FROM _timescaledb_catalog.chunk_constraint cc
INNER JOIN _timescaledb_catalog.chunk c
        ON cc.chunk_id = c.id
GROUP BY 1, 2,3 ,4
)
SELECT dc.*, ccc.*
FROM chunk_constraint_count ccc
INNER JOIN dimension_count dc
ON dc.id = ccc.hypertable_id
WHERE dc.count != ccc.count;

And this one will show the catalog entries that need to be inserted:

WITH dimension_count as (
SELECT ht.id, count(*)
FROM _timescaledb_catalog.hypertable ht
INNER JOIN _timescaledb_catalog.dimension d
        ON d.hypertable_id = ht.id
WHERE table_name = 'clicks'
GROUP BY 1),
chunk_constraint_count AS (
SELECT c.hypertable_id, cc.chunk_id, c.schema_name, c.table_name, count(*)
FROM _timescaledb_catalog.chunk_constraint cc
INNER JOIN _timescaledb_catalog.chunk c
        ON cc.chunk_id = c.id
GROUP BY 1, 2,3 ,4
)
SELECT ccc.chunk_id, tcc.dimension_slice_id, cc.constraint_name, null as hypertable_constraint_name
FROM information_schema.table_constraints tc
INNER JOIN chunk_constraint_count ccc 
ON ccc.schema_name = tc.table_schema
and ccc.table_name = tc.table_name
INNER JOIN dimension_count dc
ON dc.id = ccc.hypertable_id
INNER JOIN information_schema.check_constraints cc
ON tc.constraint_name = cc.constraint_name
INNER JOIN information_schema.check_constraints jcc
ON cc.check_clause = jcc.check_clause
AND jcc.constraint_name != cc.constraint_name
AND EXISTS (
        SELECT FROM _timescaledb_catalog.chunk_constraint
        WHERE chunk_constraint.constraint_name = jcc.constraint_name
)
INNER JOIN _timescaledb_catalog.chunk_constraint tcc
ON jcc.constraint_name = tcc.constraint_name
WHERE dc.count != ccc.count
and tc.constraint_name like 'constraint%'
and NOT EXISTS (
        SELECT FROM _timescaledb_catalog.chunk_constraint
        WHERE chunk_constraint.constraint_name = tc.constraint_name
        AND chunk_constraint.chunk_id = ccc.chunk_id
        AND chunk_constraint.hypertable_constraint_name IS NULL
);

Can you share the outputs of these queries?

Thanks,

I'm so sorry, I didn't use your hypertable name. Can we try them again? I've updated the ht names:

This release contains performance improvements and bug fixes since the 2.15.0 release. Best practice is to upgrade at the next available opportunity. **Migrating from self-hosted TimescaleDB v2.14.x and earlier** After you run `ALTER EXTENSION`, you must run [this SQL script](https://github.com/timescale/timescaledb-extras/blob/master/utils/2.15.X-fix_hypertable_foreign_keys.sql). For more details, see the following pull request [timescale#6797](timescale#6797). If you are migrating from TimescaleDB v2.15.0 or v2.15.1, no changes are required. **Bugfixes** * timescale#6975: Fix sort pushdown for partially compressed chunks. * timescale#6976: Fix removal of metadata function and update script. * timescale#6978: Fix segfault in compress_chunk with primary space partition. * timescale#6993: Disallow hash partitioning on primary column. **Thanks** * @gugu for reporting the issue with catalog corruption due to update. * @srieding for reporting an issue with partially compressed chunks and ordering on joined columns.

I see a problem in the second query, I have made a minor tweak. Can we give this a try?

So it seems like we have a winner. That query should restore your corrupt catalog. You can attempt to fix it by running the following query.

BE ADVISED: keeping a fresh backup of the database would be ideal so you can revert back to it if the catalog is still corrupt after the attempted fix.

With that said, here is the query which should insert 213 catalog tuples exactly:

WITH dimension_count as (
SELECT ht.id, count(*)
FROM _timescaledb_catalog.hypertable ht
INNER JOIN _timescaledb_catalog.dimension d
	ON d.hypertable_id = ht.id
WHERE table_name = 'clicks'
GROUP BY 1),
chunk_constraint_count AS (
SELECT c.hypertable_id, cc.chunk_id, c.schema_name, c.table_name, count(*)
FROM _timescaledb_catalog.chunk_constraint cc
INNER JOIN _timescaledb_catalog.chunk c
	ON cc.chunk_id = c.id
GROUP BY 1, 2,3 ,4
)
INSERT INTO _timescaledb_catalog.chunk_constraint
SELECT ccc.chunk_id, tcc.dimension_slice_id, cc.constraint_name, null as hypertable_constraint_name
FROM information_schema.table_constraints tc
INNER JOIN chunk_constraint_count ccc 
ON ccc.schema_name = tc.table_schema
and ccc.table_name = tc.table_name
INNER JOIN dimension_count dc
ON dc.id = ccc.hypertable_id
INNER JOIN information_schema.check_constraints cc
ON tc.constraint_name = cc.constraint_name
INNER JOIN information_schema.check_constraints jcc
ON cc.check_clause = jcc.check_clause
AND jcc.constraint_name != cc.constraint_name
AND EXISTS (
	SELECT FROM _timescaledb_catalog.chunk_constraint
	WHERE chunk_constraint.constraint_name = jcc.constraint_name
)
left JOIN lateral (
	SELECT dimension_slice_id FROM _timescaledb_catalog.chunk_constraint
	WHERE chunk_constraint.constraint_name = jcc.constraint_name
	limit 1
) as tcc ON true
WHERE dc.count != ccc.count
and tc.constraint_name like 'constraint%'
and NOT EXISTS (
	SELECT FROM _timescaledb_catalog.chunk_constraint
	WHERE chunk_constraint.constraint_name = tc.constraint_name
	AND chunk_constraint.chunk_id = ccc.chunk_id
	AND chunk_constraint.hypertable_constraint_name IS NULL
);

Please let me know does it help.

Thanks!

This release contains performance improvements and bug fixes since the 2.15.0 release. Best practice is to upgrade at the next available opportunity. **Migrating from self-hosted TimescaleDB v2.14.x and earlier** After you run `ALTER EXTENSION`, you must run [this SQL script](https://github.com/timescale/timescaledb-extras/blob/master/utils/2.15.X-fix_hypertable_foreign_keys.sql). For more details, see the following pull request [timescale#6797](timescale#6797). If you are migrating from TimescaleDB v2.15.0 or v2.15.1, no changes are required. **Bugfixes** * timescale#6975: Fix sort pushdown for partially compressed chunks. * timescale#6976: Fix removal of metadata function and update script. * timescale#6978: Fix segfault in compress_chunk with primary space partition. * timescale#6993: Disallow hash partitioning on primary column. **Thanks** * @gugu for reporting the issue with catalog corruption due to update. * @srieding for reporting an issue with partially compressed chunks and ordering on joined columns.
