| Description |
|
In a multi-UM configuration, processes such as DDLProc and DMLProc can sometimes show up in the COLD_STANDBY or the HOT_STANDBY state. For example:
It does not seem to be documented anywhere how processes may end up in this state. For example, it is not mentioned on the following pages: https://mariadb.com/kb/en/library/columnstore-multiple-user-module-guide/ https://mariadb.com/kb/en/library/managing-columnstore-module-configurations/ And the COLD_STANDBY state doesn't even seem to be mentioned here: https://mariadb.com/kb/en/library/columnstore-system-operations/#viewing-process-status |

Only loosely. This issue is about updating the MariaDB ColumnStore documentation to describe how processes end up in these states. |

The "create date" on this ticket is pre-convergence with MariaDB server. If the issue still exists in a modern version of the engine/plugin please submit a new ticket. |
