MariaDB starting with 10.5
The Information Schema THREAD_POOL_GROUPS
table was introduced in MariaDB 10.5.0.
It contains the following columns:
Column | Description |
---|---|
GROUP_ID | |
CONNECTIONS | |
THREADS | |
ACTIVE_THREADS | |
STANDBY_THREADS | |
QUEUE_LENGTH | |
HAS_LISTENER | |
IS_STALLED |
Setting thread_pool_dedicated_listener will give each group its own dedicated listener, and the listener thread will not pick up work items. As a result, the actual queue size in the table will be more exact, since IO requests are immediately dequeued from poll, without delay.
