Expand description

Configuration for the event-driven connector pipeline.

Fields§

§max_poll_records: usize

Maximum records per poll_batch() call.

§channel_capacity: usize

Channel capacity for per-source mpsc sender → coordinator.

§fallback_poll_interval: Duration

Fallback poll interval when a source returns no data_ready_notify.

§checkpoint_schedule: CheckpointSchedule

Whether checkpoints are disabled, manual-only, or periodic.

§batch_window: Duration

Sleep after the first event in a cycle to let more data accumulate.

Bounds SQL executions per second without sacrificing data. The bounded channel provides natural backpressure during the window. ZERO = no batching.

§checkpoint_timeout: Duration

Sole checkpoint-derived control-plane budget. Each connector startup stage and checkpoint barrier creates one absolute deadline from this duration; individual connectors cannot reset it.

§delivery_guarantee: DeliveryGuarantee

End-to-end delivery guarantee for the pipeline.

§cycle_budget_ns: u64

Maximum wall-clock time for a single processing cycle (nanoseconds). Default: 10ms.

§drain_budget_ns: u64

Maximum wall-clock time for the message drain phase (nanoseconds). Default: 1ms.

§query_budget_ns: u64

Maximum wall-clock time for per-query execution within a cycle (nanoseconds). Default: 8ms.

§background_budget_ns: u64

Maximum wall-clock time for background work after SQL execution (nanoseconds). Default: 5ms.

§max_input_buf_batches: usize

Per-input-port batch cap. Default: 256.

§max_input_buf_bytes: Option<usize>

Per-input-port byte cap. None = disabled.

§backpressure_policy: BackpressurePolicy

What to do when either cap is exceeded.

§shared_source_isolation: bool

Isolate queries that share a source into independent failure domains. Off: they fault and recover together; on: a fault holds back only its own offset.

§max_replay_buffer_bytes: usize

Per-source cap on the in-memory replay buffer used by shared_source_isolation. On overflow the engine falls back to whole-pipeline recovery. Ignored when the flag is off.
