> 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.
