Feature Description

Determines which transaction to roll back when a deadlock occurs.
When set to WRITE_LEAST, prioritizes rolling back transactions with less data written.
When set to START_LATEST, prioritizes rolling back later-started transactions.
It is recommended to set this parameter via the console to ensure synchronized configuration changes across all nodes. Only the parameter value on the node responsible for deadlock detection actually affects the behavior of selecting transactions to roll back, while the parameter value on other nodes does not affect this behavior.
