Abstract
Embodiments facilitate efficient recovery from an inter-stream messaging system failure by using heartbeat messages (HMs) to act as watermarks for message recovery. Embodiments insert HMs into each of the input streams at configurable regular intervals. The inter-stream router determines that a message being routed is a HM, and corresponding output HMs are generated based on the input HM. Embodiments insert a respective output HM into each of the output streams. Information indicating which output HMs have been processed from the output streams is tracked. After a failure of the inter-stream router, embodiments identify a target HM for each input stream, which is the latest HM sourced from the respective input stream that was processed from all of the output streams. After the inter-stream router restarts, the router initiates message routing, from each input stream, at the location of the respective input stream's target HM within the input stream.
