obproxy_force_parallel_query_dop

Last Updated:2026-09-04 08:23:04

obproxy_force_parallel_query_dop is used to adapt to the _force_parallel_query_dop parameter of OceanBase Database.

The _force_parallel_query_dop parameter specifies the default degree of parallelism (DOP) of SQL queries in sessions. If no PARALLEL hint is specified, the DOP of SQL queries is subject to this parameter.

Note

This parameter is introduced since ODP Enterprise Edition V3.2.11 BP1 and ODP Community Edition V4.2.0.

Attribute

Parameter type Integer
Default value 1
Value range [1,+∞)
