Data#
Gateways are by default configured to persist all events. The generated files can be referred to as event-logs: an append-only time-ordered stream of messages seen by the gateway.
Important
Event-logs capture all data seen by the gateways.
Event-logs allow for different use-cases
Historical events can be replayed in the exact same order as they occured
Simulation
Back-testing
Events can be exported to third-party solutions in near-real-time
Time-series databases, e.g. ClickHouse
Pub/Sub messaging services, e.g. Redis
The following sub-sections describes different ways to work with event-logs.
