Feature Description
This parameter is used to set the maximum threshold for the time taken to proactively switch to the primary task (including the time for migrating transactions from the old leader and sending requests to the new leader).
If the duration exceeds this threshold, it is identified as a time-consuming exception. The system increments the MySQL status metric tdstore_transfer_leader_job_cost_exception_count, which is then reported to the TDSQL Boundless console for display.
