Expand description

Unified checkpoint configuration.

Timeouts prevent a stuck sink or hung filesystem from stalling the runtime. state_inline_threshold decides per-operator whether state inlines as base64 in the JSON manifest or lands in a sidecar file. max_checkpoint_bytes caps total sidecar size; an oversized checkpoint is rejected with [LDB-6014].

Fields§

§interval: Option<Duration>

Interval between checkpoints. None = manual only.

§max_retained: usize

Number of completed checkpoints retained on disk/in object store.

§alignment_timeout: Duration

Upper bound on barrier-alignment wait at fan-in operators.

§pre_commit_timeout: Duration

Upper bound on sink pre-commit (phase 1).

§persist_timeout: Duration

Upper bound on manifest persist.

§commit_timeout: Duration

Upper bound on sink commit (phase 2).

§rollback_timeout: Duration

Upper bound on sink rollback.

§state_inline_threshold: usize

States larger than this go to a sidecar rather than base64 JSON.

§serialization_timeout: Duration

Upper bound on operator state serialization.

§max_checkpoint_bytes: Option<usize>

Cap on total sidecar bytes; None = no limit. 80% warn threshold.
