Last Updated：2026-04-14 09:41:35 Updated

rpc_period_task_interval specifies the interval for ODP to execute periodic RPC processing tasks. RPC processing tasks mainly clean up requests in invalid state in the frontend and backend.

Note

This parameter is introduced since ODP V4.3.0.

Attribute	Description
Parameter type	Time
Default value	600s
Value range	[1ms, 1d]
Effective only after ODP restart	No
