Before this commit, we acquire the metadata locks on the reference
tables while removing/disabling a node on all the MX nodes.
Although it has some marginal benefits, such as a concurrent
modification during remove/disable node blocks, instead of erroring
out, the drawbacks seems worse. Both citus_remove_node and citus_disable_node
are not tolerant to multiple node failures.
With this commit, we relax the locks. The implication is that while
a node is removed/disabled, users might see query errors. On the
other hand, this change becomes removing/disabling nodes more
tolerant to multiple node failures.
When refactoring storage layer in #4907, we deleted the code that allows
overwriting a disk page previously written but not known by metadata.
Readers can see the change that introduced the code allows doing so in
commit a8da9acc63.
The reasoning was that; as of 10.2, we started aligning page
reservations (`AlignReservation`) for subsequent writes right after
allocating pages from disk. That means, even if writer transaction
fails, subsequent writes are guaranteed to allocate a new page and write
to there. For this reason, attempting to write to a page allocated
before is not possible for a columnar table that user created when using
v10.2.x.
However, since the older versions of columnar doesn't do that, following
example scenario can still result in writing to such disk page, even if
user now upgraded to v10.2.x. This is because, when upgrading storage to
2.0 (`ColumnarStorageUpdateIfNeeded`), we calculate `reservedOffset` of
the metapage based on the highest used address known by stripe
metadata (`GetHighestUsedAddressAndId`). However, stripe metadata
doesn't have entries for aborted writes. As a result, highest used
address would be computed by ignoring pages that are allocated but not
used.
- User attempts writing to columnar table on Citus v10.0x/v10.1x.
- Write operation fails for some reason.
- User upgrades Citus to v10.2.x.
- When attempting to write to same columnar table, they hit to "attempt
to write columnar data .." error since write operation done in the
older version of columnar already allocated that page, and now we are
overwriting it.
For this reason, with this commit, we re-do the change done in
a8da9acc63.
And for the reasons given above, it wasn't possible to add a test for
this commit via usual code-paths. For this reason, added a UDF only for
testing purposes so that we can reproduce the exact scenario in our
regression test suite.
During pg upgrades, we have seen that it is not guaranteed that a
columnar table will be created after metadata objects got created.
Prior to changes done in this commit, we had such a dependency
relationship in `pg_depend`:
```
columnar_table ----> columnarAM ----> citus extension
^ ^
| |
columnar.storage_id_seq -------------------- |
|
columnar.stripe -------------------------------
```
Since `pg_upgrade` just knows to follow topological sort of the objects
when creating database dump, above dependency graph doesn't imply that
`columnar_table` should be created before metadata objects such as
`columnar.storage_id_seq` and `columnar.stripe` are created.
For this reason, with this commit we add new records to `pg_depend` to
make columnarAM depending on all rel objects living in `columnar`
schema. That way, `pg_upgrade` will know it needs to create those before
creating `columnarAM`, and similarly, before creating any tables using
`columnarAM`.
Note that in addition to inserting those records via installation script,
we also do the same in `citus_finish_pg_upgrade()`. This is because,
`pg_upgrade` rebuilds catalog tables in the new cluster and that means,
we must insert them in the new cluster too.
- [x] Add some more regression test coverage
- [x] Make sure returning works fine in case of
local execution + remote execution
(task->partiallyLocalOrRemote works as expected, already added tests)
- [x] Implement locking properly (and add isolation tests)
- [x] We do #shardcount round-trips on `SerializeNonCommutativeWrites`.
We made it a single round-trip.
- [x] Acquire locks for subselects on the workers & add isolation tests
- [x] Add a GUC to prevent modification from the workers, hence increase the
coordinator-only throughput
- The performance slightly drops (~%15), unless
`citus.allow_modifications_from_workers_to_replicated_tables`
is set to false
Drop extension might cascade to columnar.options before dropping a
columnar table. In that case, we were getting below error when opening
columnar.options to delete records for the columnar table that we are
about to drop.: "ERROR: could not open relation with OID 0".
I somehow reproduced this bug easily when upgrading pg, that is why
adding added the test to after_pg_upgrade_schedule.
We recently introduced a set of patches to 10.2, and introduced 10.2-4
migration version. This migration version only resides on `release-10.2`
branch, and is missing on our default branch. This creates a problem
because we do not have a valid migration path from 10.2 to latest 11.0.
To remedy this issue, I copied the relevant migration files from
`release-10.2` branch, and renamed some of our migration files on
default branch to make sure we have a linear upgrade path.
Before this commit, we required the user to be owner of the shard/table
in order to call lock_shard_resources.
However, that is too restrictive. We can have users with GRANTS
to the table who are not owners of the tables/shards.
With this commit, we allow such patterns.

This PR is fixing 2 separate issues related to the local run of citus upgrade tests.
d3e7c825ab fixes the issue that, with our new testing infrastructure, we moved/renamed some of existing folders. This created a problem for local runs of citus upgrade tests since some paths were sensitive to such changes. This commit tries to make it more generic so that this issue is less likely to happen in the future, while also fixing the current issue.
93de6b60c3 we are fixing an issue that a new environment variable was added for citus upgrade tests, which is defined in the CI. 0cb51f8c37/.circleci/config.yml (L294)
This environment variable wasn't set in our local runs hence it would create problems. Instead of defining this environment variable in the local run, we change the citus_upgrade run command to use an existing env variable, which is now also set in the CI.
We fixed some crashes a while back that would only occur in cases where
the value of a distribution column would have result in a high or a very
low hash value. This adds a regression test for those crashes.
This test starts passing because of PR #4508, to be precise commit:
24e60b44a1
When I undo that commit this newly added test starts failing. This adds
this test to make sure we don't regress on this again.
There is a vulnerability in mitmproxy with the version we are using.
It would be hard to exploit anything with regards to the artifacts we ship as its only used in our test suite. Still its good hygiene to _not_ use software with known vulnerabilities.
This PR updates the version of python, mitmproxy and the crypto libraries used.
The latest version of mitmproxy for python 3.6 is not patched, hence the upgrade of python.
For our CI images this cascades into upgrading debian as well :)
For CI we bake these versions in our images so we need to update them as well.
Changes to the CI images: https://github.com/citusdata/the-process/pull/65
In the past, we allowed users to manually switch to 1PC
(e.g., one phase commit). However, with this commit, we
don't. All multi-shard modifications are done via 2PC.
With Citus 9.0, we introduced `citus.single_shard_commit_protocol` which
defaults to 2PC.
With this commit, we prevent any user to set it to 1PC and drop support
for `citus.single_shard_commit_protocol`.
Although this might add some overhead for users, it is already the default
behaviour (so less likely) and marking placements as INVALID is much
worse.
- citus_get_all_dependencies_for_object: emulate what Citus
would qualify as
dependency when adding

- citus_get_dependencies_for_object: emulate what Citus would qualify

Example use:
```SQL

SELECT
pg_identify_object(t.classid, t.objid, t.objsubid)
FROM
(SELECT * FROM pg_get_object_address('table', '{test}', '{}')) as addr
JOIN LATERAL

ON TRUE

```
To run tests in parallel use:
```bash
make check-arbitrary-configs parallel=4
```
To run tests sequentially use:
```bash
make check-arbitrary-configs parallel=1
```
To run only some configs:
```bash
make check-arbitrary-base CONFIGS=CitusSingleNodeClusterConfig,CitusSmallSharedPoolSizeConfig
```
To run only some test files with some config:
```bash
make check-arbitrary-base CONFIGS=CitusSingleNodeClusterConfig EXTRA_TESTS=dropped_columns_1
```
To get a deterministic run, you can give the random's seed:
```bash
make check-arbitrary-configs parallel=4 seed=12312
```
The `seed` will be in the output of the run.
In our regular regression tests, we can see all the details about either planning or execution but this means
we need to run the same query under different configs/cluster setups again and again, which is not really maintanable.
When we don't care about the internals of how planning/execution is done but the correctness, especially with different configs
this infrastructure can be used.
With `check-arbitrary-configs` target, the following happens:
- a bunch of configs are loaded, which are defined in `config.py`. These configs have different settings such as different shard count, different citus settings, postgres settings, worker amount, or different metadata.
- For each config, a separate data directory is created for tests in `tmp_citus_test` with the config's name.
- For each config, `create_schedule` is run on the coordinator to setup the necessary tables.
- For each config, `sql_schedule` is run. `sql_schedule` is run on the coordinator if it is a non-mx cluster. And if it is mx, it is either run on the coordinator or a random worker.
- Tests results are checked if they match with the expected.
When tests results don't match, you can see the regression diffs in a config's datadir, such as `tmp_citus_tests/dataCitusSingleNodeClusterConfig`.
We also have a PostgresConfig which runs all the test suite with Postgres.
By default configs use regular user, but we have a config to run as a superuser as well.
So the infrastructure tests:
- Postgres vs Citus
- Mx vs Non-Mx
- Superuser vs regular user
- Arbitrary Citus configs
When you want to add a new test, you can add the create statements to `create_schedule` and add the sql queries to `sql_schedule`.
If you are adding Citus UDFs that should be a NO-OP for Postgres, make sure to override the UDFs in `postgres.sql`.
You can add your new config to `config.py`. Make sure to extend either `CitusDefaultClusterConfig` or `CitusMXBaseClusterConfig`.
On the CI, upon a failure, all logfiles will be uploaded as artifacts, so you can check the artifacts tab.
All the regressions will be shown as part of the job on CI.
In your local, you can check the regression diffs in config's datadirs as in `tmp_citus_tests/dataCitusSingleNodeClusterConfig`.

* Add udf to include shardId in broken partition shard index names
* Address reviews: rename index such that operations can be done on it
* More comprehensive index tests
* Final touches and formatting
A write operation might trigger index deletion if index already had
dead entries for the key we are about to insert.
There are two ways of index deletion:
a) simple deletion
b) bottom-up deletion (>= pg14)
Since columnar_index_fetch_tuple never sets all_dead to true,
columnarAM doesn't ever expect to receive simple deletion requests
(columnar_index_delete_tuples) as we don't mark any index entries
as dead.
However, since columnarAM doesn't delete any dead entries via simple
deletion, postgres might ask for a more comprehensive deletion
(i.e.: bottom-up) at some point when pg >= 14.
So with this commit, we start gracefully ignoring bottom-up deletion
requests made to columnar_index_delete_tuples.
Given that users can anyway "VACUUM FULL" their columnar tables,
we don't see any problem in ignoring deletion requests.
* Make (columnar.stripe) first_row_number index a unique constraint
Since stripe_first_row_number_idx is required to scan a columnar
table, we need to make sure that it is created before doing anything
with columnar tables during pg upgrades.
However, a plain btree index is not a dependency of a table, so
pg_upgrade cannot guarantee that stripe_first_row_number_idx gets
created when creating columnar.stripe, unless we make it a unique
"constraint".
To do that, drop stripe_first_row_number_idx and create a unique
constraint with the same name to keep the code change at minimum.
* Add more pg upgrade tests for columnar
* Fix a logic error in uprade_columnar_after test

We were trying to find the cause for a strange update bug. We thought
`pg_upgrade` succeeded and then were surprised that certain data was not
in the database after the upgrade. Instead `pg_upgrade` had failed
halfway through with an actionable error. It took us pretty long to
realise this.
This commit adds checking of exit codes to a lot more subprocess
executions. That should make debugging in the future much easier.
Considering all code-paths that we might interact with a columnar table,
add `CheckCitusVersion` calls to tableAM callbacks:
- initializing table scan (`columnar_beginscan` & `columnar_index_fetch_begin`)
- setting a new filenode for a relation (storage initializiation or a table rewrite)
- truncating the storage
- inserting tuple (single and multi)
Also add `CheckCitusVersion` call to:
- drop hook (`ColumnarTableDropHook`)
- `alter_columnar_table_set` & `alter_columnar_table_reset` UDFs
* Columnar: separate plain and exec quals.
Make a clear separation between plain quals, which contain constants
or extern params; and exec quals, which contain exec params and can't
be evaluated until a rescan.
Fixes#5258.
* more vanilla tests

When performing a partition-wise join, the planner will adjust paths
parameterized by the parent rel to instead parameterize by the child
rel directly. When this reparameterization happens, we also need to
adjust the join quals to reference the child rather than the parent.
Fixes#5257.
Not flush pending writes if given tid belongs to a "flushed" or
"aborted" stripe write, or to an "in-progress" stripe write of
another backend.
That way, we would reduce the cases where we flush single-tuple
stripes during index scan.
To do that, we follow below steps for index look-up's:
- Do not flush any pending writes and do stripe metadata look-up for
given tid.
If tuple with tid is found, then no need to do another look-up
since we already found the tuple without needing to flush pending
writes.
- If tuple is not found without flushing pending writes, then we have two
scenarios:
- If given tid belongs to a pending write of my backend, then do stripe
metadata look-up for given tid. But this time first **flush any pending
writes**.
- Otherwise, just return false from `index_fetch_tuple` since flushing
pending writes wouldn't help.
With 5825c44d5f, we made the changes to
skip aborted writes when scanning a columnar table.
However, looks like we forgot to handle such cases for the very first
call made to columnar_getnextslot. That means, that commit only
considered the intermediate stripe read operations.
However, functions called by columnar_getnextslot to find first stripe
to read (ColumnarBeginRead & ColumnarRescan) were not caring about
those aborted writes.
To fix that, we teach AdvanceStripeRead to find the very first stripe
to read, and then start using it where were blindly calling
FindNextStripeByRowNumber.
Previously, even when `EXPLAIN` output tells that we will do
index-only scan, it was never the case since columnar tables
don't have the visibility fork that postgres is looking for.
For this reason, visibility check done in
`IndexOnlyNext->VM_ALL_VISIBLE`
code-path was always returning false and postgres was reading
the tuple from the columnar relation itself.
Previously, for regular table scans, we were setting `RelOptInfo->partial_pathlist`
to `NIL` via `set_rel_pathlist_hook` to discard scan `Path`s that need to use any
parallel workers, this was working nicely.
However, when building indexes, this hook doesn't get called so we were not
able to prevent spawning parallel workers when building an index. For this
reason, 9b4dc2f804 added basic
implementation for `columnar_parallelscan_*` callbacks but also made some
changes to skip using those workers when building the index.
However, now that we are doing stripe reservation in two stages, we call
`heap_inplace_update` at some point to complete stripe reservation.
However, postgres throws an error if we call `heap_inplace_update` during
a parallel operation, even if we don't actually make use of those workers.
For this reason, with this pr, we make sure to not generate scan `Path`s that
need to use any parallel workers by using `get_relation_info_hook`.
This is indeed useful to prevent spawning parallel workers during index builds.
If it is certain that we will not use any `parallel_worker`s for a columnar table,
then stripe entries inserted by aborted transactions become visible to
`SnapshotAny` and that causes `REINDEX` to fail by throwing a duplicate key
error.
To fix that:
* consider three states for a stripe write operation:
"flushed", "aborted", or "in-progress",
* make sure to have a clear separation between them, and
* act according to those three states when reading from a columnar table
Since PG14 we can now use binary encoding for arrays and composite types
that contain user defined types. This was fixed in this commit in
Postgres: 670c0a1d47
This change starts using that knowledge, by not necessarily falling back
to text encoding anymore for those types.
While doing this and testing a bit more I found various cases where
binary encoding would fail that our checks didn't cover. This fixes
those cases and adds tests for those. It also fixes EXPLAIN ANALYZE
never using binary encoding, which was a leftover of workaround that
was not necessary anymore.
Finally, it changes the default for both `citus.enable_binary_protocol`
and `citus.binary_worker_copy_format` to `true` for PG14 and up. In our
cloud offering `binary_worker_copy_format` already was true by default.
`enable_binary_protocol` had some bug with MX and user defined types,
this bug was fixed by the above mentioned fixes.
- get_missing_time_partition_ranges: Gets the ranges of missing partitions for the given table, interval and range unless any existing partition conflicts with calculated missing ranges.
- create_time_partitions: Creates partitions by getting range values from get_missing_time_partition_ranges.
- drop_old_time_partitions: Drops partitions of the table older than given threshold.
* Rename RecostColumnarPaths to CostColumnarPaths
* Rename RecostColumnarIndexPath to CostColumnarIndexPath
* Reorder args of CostColumnarScan to align with other two costing functions
* Not adjust index scan start-up cost
* Rename ColumnarIndexScanAddTotalCost to ColumnarIndexScanAdditionalCost
* Reflect that index scan will at least read one stripe in totalCost calculation
* Organize declarations in columnar_customscan.c
In PG 14, procedures can have OUT parameters. In Citus' procedure
delegation framework, we need to adjust the function expression
to get the outargs parameters.
Releven PG change:
e56bce5d43
It seems like there is a problem with Postgres14 with SELECT DISTINCT
COUNT. The issue is reported to Postgres and an alternative output is
added. We can remove the alternative output when the issue is fixed on
PG. If this is not an issue on PG(which is unlikely) we should consider
some other solution.
In order to avoid adding an alternative output, a function to check if a
given explan plan has a single task added. This doesn't change what the
changed tests intend to do.
Postgres changed stats expression types as of PG14. Hence we needed to
write the AppendColumnNames method. Also they removed the error on PG
side so we remove it as well.
Relevant commits on pg14:
a4d75c86bf15220df22de0a92c819ecef9db3849
388e75ad33489b77cfb9a8590a91e9287d8fb960
When queryId is not 0 and verbose is true, the query identifier is
emitted to the explain output. This is breaking Postgres outputs.
We disable de query identifier calculation in the tests.
Commit on PG that introduced the query identifier in the explain output:
4f0b0966c866ae9f0e15d7cc73ccf7ce4e1af84b
There was a small part in multi_partitioning that would need an
alternative output for pg14. Instead of adding an alternative for the
whole file, we created a new file, called partition_wise_join.sql and
added the alternative output for that.
When we check the exact version of the seg extension, it becomes a
problem when its version changes, such as from 1.3 to 1.4. So now we
modified the changes to check for that the version is the same in all
the cluster.
Postgres tightened up its checks for invalid GUC names hence we started
to get an alternative output for one of our tests. We add an alternative
output since the file is relatively small.

fix array_cat_agg for pg upgrades
array_cat_agg now needs to take anycompatiblearray instead of anyarray
because array_cat changed its type from anyarray to anycompatiblearray
with pg14.
To handle upgrades correctly, we drop the aggregate in
citus_pg_prepare_upgrade. To be able to drop it, we first remove the
dependency from pg_depend.
Then we create the right aggregate in citus_finish_pg_upgrade and we
also add the dependency back to pg_depend.
Allow ColumnarScans to push down join quals by generating
parameterized paths. This significantly expands the utility of chunk
group filtering, making a ColumnarScan behave similar to an index when
on the inner of a nested loop join.
Also, evaluate all parameters on beginscan/rescan, which also works
for external parameters.
Fixes#4488.
Previously, we were doing `first_row_number` reservation for the first
row written to current `WriteState` but were doing `stripe_id`
reservation when flushing the `WriteState` and were inserting the
related record to `columnar.stripe` at that time as well.
However, inserting `columnar.stripe` record at flush-time is
problematic. This is because, as told in #5160, if relation has
any index-based constraints and if there are two concurrent
writes that are inserting conflicting key values for that constraint,
then postgres relies on `tableAM->fetch_index_tuple`
(=`columnar_fetch_index_tuple`) callback to return `true` when
indexAM is checking against possible constraint violations.
However, pending writes of other backends are not visible to concurrent
sessions in columnar since we were not inserting the stripe metadata
record until flushing the stripe.
With this commit, we split stripe reservation into two phases:
i) Reserve `stripe_id` and insert a "dummy" record to `columnar.stripe`
at the very same time we reserve `first_row_number`, i.e. when writing
the first row to the current `WriteState`.
ii) At flush time, do the storage level allocation and complete the
missing fields of the dummy record inserted into `columnar.stripe`
during i).
That way, any concurrent writes would be able to check against possible
constraint violations by using `SnapshotDirty` when scanning
`columnar.stripe`.
Note that `columnar_fetch_index_tuple` still wouldn't be able to fill
the output tupleslot for the requested tid but it would at least return
`true` for such index look-up's and we believe this should be sufficient
for the caller indexAM callback to make the concurrent writer block on
prior one.
That is how we fix#5160.
Only downside of reserving `stripe_id` at the same time we reserve
`first_row_number` is that now any aborted writes would also waste
some amount of `stripe_id` as in the case of `first_row_number` but
we are just wasting them one-by-one.
Considering the fact that we waste `first_row_number` by the amount
stripe row limit (=150k by default) in such cases, this shouldn't be
important at all.
Before starting to scan a columnar table, we always flush the pending
writes to disk.
However, we increment command counter after modifying metadata tables.
On the other hand, now that we _don't always use_ xact snapshot to scan
a columnar table, writes that we just flushed might not be visible to
the query that just flushed pending writes to disk since curcid of
provided snapshot would become smaller than the command id being used
when modifying metadata tables.
To give an example, before this change, below was a possible scenario
due to the changes that we made to use the correct snapshot.
```sql
CREATE TABLE t(a int, b int) USING columnar;
BEGIN;
INSERT INTO t VALUES (5, 10);
SELECT * FROM t;
┌───┬───┐
│ a │ b │
├───┼───┤
└───┴───┘
(0 rows)
SELECT * FROM t;
┌───┬────┐
│ a │ b │
├───┼────┤
│ 5 │ 10 │
└───┴────┘
(1 row)
```
The logging of the amount of ignored moves crashed when no distributed
tables existed in a cluster. This also fixes in passing that the logging
of ignored moves logs the correct number of ignored moves if there
exist multiple colocation groups and all are rebalanced at the same time.

In our testing infra structure, even though we use pinned versions of postgres, the auxiliary libraries might pull in newer versions. This is for example the case for libpq, which will now use the libpq libraries from 14beta3.
The changes in this PR are a lot due to the libpq changes.
We also have changed the citus version that is used as a base for the citus upgrades, from 10.0 to 10.1 . This caused columnar to enforce some extra limits on the settings, which conflicted with our upgrade tests.
The changes in failure tests are due to the libpq changes.
There are also a lot of changes on isolation tests outputs, hence we
updated all of them.

* We were anyway not testing reserved_offset in any of those tests
but other fields.
* This only happens with compressed columnar tables and is because the
libzstd/liblz4 versions that we have on exttester ci image might be different
than what we might have on our local environments.
