Interface InboxOptions

Park a delivery after this many handler failures (1–1000), acknowledging it so a Kafka partition or a NATS consumer is no longer blocked. Absent (the default), a failure is rethrown and the broker's own retry budget applies — RabbitMQ and Redis Streams retry and dead-letter, while NATS redelivers without limit and Kafka blocks the partition, so set it there. On RabbitMQ and Redis Streams both budgets apply and the smaller wins: keep it at or below consumerRetry.maxAttempts (or disable consumerRetry), or the broker dead-letters before the inbox parks.

Largest envelope, in UTF-8 bytes, stored on a parked marker for release('retry'); a larger one is parked without it. 0 stores none. Default 262144.

The retention purge schedule.

How long a marker is kept, in milliseconds (at least 60 000). A redelivery older than this is processed again, so it must exceed the broker's redelivery window plus the outbox's re-send window. Default 7 days. Parked markers are purged by the same window, envelope included: release or discard a parked delivery before it ages out.

The store every inbox subscription records deliveries through.

Bound on every store call the inbox makes except the handler's own transaction, in milliseconds. Default 5000.
