merger_switch_leader_duration_time

Last Updated：2025-11-27 02:38:06 Updated

Note

OceanBase Database V4.x does not support zone-level rotating compactions. Therefore, you do not need to specify the interval for a batch leader switchover in a major compaction. This parameter has been deprecated since OceanBase Database V4.0.0.

merger_switch_leader_duration_time specifies the interval for a batch leader switchover in a daily compaction.

Attribute	Description
Type	Time
Default value	`3m`, indicating 3 minutes.
Value range	[0s, 30m]
Effective upon OBServer node restart	No
