Each Deployment in Ververica Platform has an event log attached to it. The event log reports the state of operations such as state transitions that are executed asynchronously.
A Flink Job can switch to an erroneous state at any time, requiring a state transition back to the desired state. Those errors and subsequent transitions are also reported in the event log.
The event log exposes events both in a human readable way and with a machine-readable unique identifier as part of the event metadata.
