Checkpointing

1 GoKawiil brief on this topic

New durable execution method skips history replay for recovery

A developer has introduced Transparent Continuation Checkpointing (TCC), a prototype recovery approach for durable execution systems that captures a program's live continuation at checkpoints instead of replaying stored execution history after a failure. On restart, the runtime loads the committed continuation and resumes directly, rather than re-running prior steps to reconstruct state. The prototype already supports durable effects, external waits, child executions, cancellation, and crash recovery.
