Environment
- Version: Starting seekdb (OceanBase seekdb 1.2.0.0) source revision 100000222026032420-bde98aeaa8740119c4a2aa420138c838312e6708.seekdb...
Description
Standby read performance is poor. Additionally, there is a performance difference observed before and after a primary-standby switchover operation.
Impact
Degraded read performance on the standby node and inconsistent performance during role transitions, potentially affecting application service levels and failover reliability.
