Implements worker_save_query_explain_analyze and worker_last_saved_explain_analyze.
worker_save_query_explain_analyze executes and returns results of query while
saving its EXPLAIN ANALYZE to be fetched later.
worker_last_saved_explain_analyze returns the saved EXPLAIN ANALYZE result.
If we want to get necessary lockmode for a relation RangeVar within
a query, we can get the lockmode easily from the RangeVar itself (if
pg version >= 12).
However, if we want to decide the lockmode appropriate for the
"query", we can derive this information by using GetQueryLockMode
according to the code comment from RangeTblEntry->rellockmode.
Implements a new `TupleDestination` interface to allow custom tuple processing per task.
This can be specially useful if a task contains multiple queries. An example of this EXPLAIN
ANALYZE, where it needs to add some UDF calls to the query to fetch the explain output
from worker after fetching the actual query results.
We should check the remove type in IsDropCitusStmt because if the remove
type is not OBJECT_EXTENSION then the stored objects in
dropStmt->objects may not be of type Value. This was crashing PG-13.
Also rename the method as IsDropCitusExtensionStmt.
To reduce code duplication, implement function that pushes search_path
to be NIL and sets addCatalog to true so that all objects outside of
pg_catalog will be schema-prefixed.
Append IF NOT EXISTS to CREATE SERVER commands generated by
pg_get_serverdef_string function when deparsing an existing server
object that a foreign table depends.
* Error out if creating a citus table from a table having triggers already.
* Error out for CREATE TRIGGER commands that are run on citus tables.
* Introduce the ability to deparse CREATE TRIGGER commands needed to recreate triggers on a table.
SELECT_TASK is renamed to READ_TASK as a SELECT with modifying CTEs will be a MODIFYING_TASK
RouterInsertJob: Assert originalQuery->commandType == CMD_INSERT
CreateModifyPlan: Assert originalQuery->commandType != CMD_SELECT
Remove unused function IsModifyDistributedPlan
DistributedExecution, ExecutionParams, DistributedPlan: Rename hasReturning to expectResults
SELECTs set expectResults to true
Rename CreateSingleTaskRouterPlan to CreateSingleTaskRouterSelectPlan
Do not release AccessShareLock when closing pg_constraint to prevent
modifications to be done on pg_constraint to make sure that caller
will process valid foreign key constraints through the transaction.
With this commit:
You can trigger two types of hammerdb benchmark jobs:
-ch_benchmark (analytical and transactional queries)
-tpcc_benchmark (only transactional queries)
Your branch will be run against `master` branch.
In order to trigger the jobs prepend `ch_benchmark/` or `tpcc_benchmark/` to your branch and push it.
For example if you were running on a feature/improvement branch with name `improve/adaptive_executor`. In order to trigger a tpcc benchmark, you can do the following:
```bash
git checkout improve/adaptive_executor
git checkout -b tpcc_benchmark/improve/adaptive_executor
git push origin tpcc_benchmark/improve/adaptive_executor # the tpcc benchmark job will be triggered.
```
You will see the results in a branch in [https://github.com/citusdata/release-test-results](https://github.com/citusdata/release-test-results).
The branch name will be something like: `delete_me/citusbot_tpcc_benchmark_rg/<date>/<date>`.
The resource groups will be deleted automatically but if the benchmark fails, they won't be deleted(If you don't see the results after a reasonable time, it might mean it failed, you can check the resource usage from portal, if it is almost 0 and you didn't see the results, it means it probably failed). In that case, you will need to delete the resource groups manually from portal, the resource groups are `citusbot_ch_benchmark_rg` and `citusbot_tpcc_benchmark_rg`.
Instead of using the git tag that is reachable from the HEAD commit,
use the exactly matching tag in citus_version().
For the other branches (including the master), just use name of the
current branch that we are installing citus and sha of the HEAD.
This is because, we do not tag the branches except the release ones.
That way, we won't see v9.2.3-DO-NOT-INSTALL tag anymore in the output
of the citus_version();
This PR removes ExecuteUtilityTaskListWithoutResults and uses the same
path for local execution via ExecuteTaskListExtended.
ExecuteUtilityTaskList is added. ExecuteLocalTaskListExtended now has a
parameter for utility commands so that it can call the right method. In
order not to change the existing calls,
ExecuteTaskListExtendedInternal is added, which is the main method that
runs the execution, via local and remote execution.
