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).
When this threshold is exceeded, the operation is deemed to have exceeded the time limit, and the MySQL status metric tdstore_transfer_leader_job_cost_exception_count will be incremented. This metric will be reported and displayed on the TDSQL Boundless console.
