      Description

      If a machine gets bogged down with 30,000 dead tasks, replaying the checkpoints can be very costly because they're spread across 30,000 x potentially many different checkpoint files. Investigate to see if there's an abstraction (e.g. a SQLiteRecordWriter) that fits nicely in the system that could provide better performance.
