MariaDB starting with 10.5.2
The events_transactions_summary_by_account_by_event_name table was introduced in MariaDB 10.5.2.

| HOST | char(60) | Host for which summary is generated. |
| EVENT_NAME | varchar(128) | Event name for which summary is generated. |
| COUNT_STAR | bigint(20) unsigned | The number of summarized events. This value includes all events, whether timed or nontimed. |
| SUM_TIMER_WAIT | bigint(20) unsigned | The total wait time of the summarized timed events. This value is calculated only for timed events because nontimed events have a wait time of NULL. The same is true for the other xxx_TIMER_WAIT values. |
