The table contains the following columns:

<<style class="darkheader-nospace-borders">>
|= 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.   |
