Automatically trigger a minor compaction

This topic describes how a minor compaction is automatically triggered.

When you create a tenant, you can specify the memory for the tenant. The memory of a tenant consists of scalable memory and a MemTable. When the usage of the MemTable of a tenant reaches the limit specified by memstore_limit_percentage * freeze_trigger_percentage, a freeze (the preparation for a minor compaction) is automatically triggered. Then, the system schedules a minor compaction. A major compaction is automatically triggered when specified conditions are met during the minor compaction. For more information, see Automatically trigger a major compaction.

For more information about the memstore_limit_percentage and freeze_trigger_percentage parameters, see Modify minor compaction settings.
