When the GROUP_CONCAT() function is used to produce relatively long strings, excessive memory can be used, which can cause PrimProc to crash with a segmentation fault. (, )
In previous releases, this issue can cause various types of messages to appear in the ColumnStore logs prior to the crash, such as:
In previous releases, this issue can cause clients to see the following error message:
Starting with this release, less memory should be used in this scenario.
When multiple ColumnStore threads or processes try to access a managed shared memory segment for the Extent Map concurrently, a read/write conflict can cause the processes to crash with a segmentation fault due to a race condition. ()
In previous releases, cpimport, PrimProc, and DMLProc were observed to crash in this scenario.
Starting with this release, the internal RWLock is upgraded to a write lock when a shared memory segment remap is initiated (such as by a long running cpimport job), thus avoiding this read/write conflict.

When exporting data from a ColumnStore table using SELECT .. INTO OUTFILE or adding data to a ColumnStore table from another ColumnStore table using INSERT .. SELECT, if the size of the ColumnStore table exceeds the amount of RAM on the server, the PrimProc process uses all of the available memory, which cause the out-of-memory (OOM) killer to kill the process and results in the following error: (MCOL-5489)
When the JSON_ARRAYAGG() function is used to produce long strings, excessive memory can be used, which can cause PrimProc to crash with a segmentation fault. (MCOL-5491)
In previous releases, this issue can cause various types of messages to appear in the ColumnStore logs prior to the crash, such as:
In previous releases, this issue can cause clients to see the following error message:
Starting with this release, less memory should be used in this scenario.
When a node communicates with itself over memory, the node effectively has an unlimited message queue, which causes memory usage to increase until the out-of-memory (OOM) killer kills the process. (MCOL-5499)
In previous releases, when a node communicated with itself over memory, the FlowControl mechanism was effectively disabled. Without FlowControl, if a slow consumer exists somewhere in the query execution pipeline, the Distributed Engine Communication (DEC) receive queue can be overloaded.
Starting with this release, FlowControl is enabled when a node communicates with itself over memory.
When executing a query that contains multiple nested SELECT statements that involve a UNION in the inner SELECT statements, an error is returned when columns with the same name are referenced by alias. (MCOL-5357)
In previous releases, an error is raised similar to:
When columnstore_use_import_for_batchinsert is enabled, the LOAD DATA INFILE statement loads values incorrectly for the MEDIUMINT, TIME, and TIMESTAMP data types. (MCOL-5480)
When using the columnstore_info.load_from_s3 stored procedure, even if the data is successfully loaded to the ColumnStore table, the procedure reports an import failure: (MCOL-5509)
When using the columnstore_info.load_from_s3 stored procedure, if cpimport fails, the user connection hangs until the connection times out without any error messages. (MCOL-5510)
Starting with this release, the following error message is raised:
When performing a join with a large table, the post-join filters are not applied. (MCOL-5512)
In previous releases, this could cause results to be incorrect.

Support added for loading data from AWS S3 via a UDF columnstore_info.load_from_s3 which allows data loading with cpimport for those with no access to the command line. (MCOL-5013)
Allow pushdown of queries involving UNION in outer SELECT to ColumnStore engine. (MCOL-4901)
MariaDB Enterprise ColumnStore 23.02.1 is confirmed to be compatible with TPC-H benchmark tests.
Starting with this release, GROUP BY handler is disabled by default. GROUP BY pushdown may produce unexpected results. In prior releases, GROUP BY handler was rarely used because it was last in precedence. ()
UNION ALL with wrapped selects supports GROUP BY clause. ()
UNION with signed and unsigned integer types is supported. ()
UNION operations that can overflow the maximum supported DECIMAL precision of 38 digits generate the following error: ()
