{% hint style="info" %}
The `events_transactions_summary_by_account_by_event_name` table is available from MariaDB 10.5.2.
{% endhint %}
The `events_transactions_summary_by_account_by_event_name` table contains information on transaction events aggregated by account and event name.
The table contains the following columns:
| Column | Type | Description |
| ----------------------- | ------------------- | ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------ |
| USER | char(32) | User for which summary is generated. |
| 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. |
| MIN\_TIMER\_WAIT | bigint(20) unsigned | The minimum wait time of the summarized timed events. |
| AVG\_TIMER\_WAIT | bigint(20) unsigned | The average wait time of the summarized timed events. |
| MAX\_TIMER\_WAIT | bigint(20) unsigned | The maximum wait time of the summarized timed events. |
| COUNT\_READ\_WRITE | bigint(20) unsigned | The total number of only READ/WRITE transaction events. |
| SUM\_TIMER\_READ\_WRITE | bigint(20) unsigned | The total wait time of only READ/WRITE transaction events. |
| MIN\_TIMER\_READ\_WRITE | bigint(20) unsigned | The minimum wait time of only READ/WRITE transaction events. |
| AVG\_TIMER\_READ\_WRITE | bigint(20) unsigned | The average wait time of only READ/WRITE transaction events. |
| MAX\_TIMER\_READ\_WRITE | bigint(20) unsigned | The maximum wait time of only READ/WRITE transaction events. |
| COUNT\_READ\_ONLY | bigint(20) unsigned | The total number of only READ ONLY transaction events. |
| SUM\_TIMER\_READ\_ONLY | bigint(20) unsigned | The total wait time of only READ ONLY transaction events. |
| MIN\_TIMER\_READ\_ONLY | bigint(20) unsigned | The minimum wait time of only READ ONLY transaction events. |
| AVG\_TIMER\_READ\_ONLY | bigint(20) unsigned | The average wait time of only READ ONLY transaction events. |
| MAX\_TIMER\_READ\_ONLY | bigint(20) unsigned | The maximum wait time of only READ ONLY transaction events. |
