Table rotation is used by Event Management, by default, to contain the growth of event [em_event] tables within the rotation table group.

About this task

Table rotation ensures that event tables grow to a reasonable size.

Each table rotation has a schedule, according to which new data is written to one of the tables in the rotation group. A table rotation group includes the original table plus several additional tables. After the rotation procedure has written the last table in a rotation, the rotation overwrites the first table in the rotation. By default, the table rotation for Event Management is to rotate the em_table to an offload table and the base table cleanup takes place after seven table rotations.
