Important
The wait events and thread states in this section are specific to Aurora MySQL. Use the information in this section to tune only Amazon Aurora, not Amazon RDS for MySQL.
Some wait events in this section have no analogs in the open source versions of these database engines. Other wait events have the same names as events in open source engines, but behave differently. For example, Amazon Aurora storage works different from open source storage, so storage-related wait events indicate different resource conditions.
