Subject Re: [ANNOUNCE] Flink 1.0.0 has been released
Date Wed, 09 Mar 2016 11:35:20 GMT
@Igor: State from the CEP library (like what was the last observed event
for a certain ID or so) is kept in Flink's state mechanisms (the key/value
state)

Have a look at these docs for details:
  - Working with State:
https://ci.apache.org/projects/flink/flink-docs-release-1.0/apis/streaming/state.html
  - Fault tolerance in general:
https://ci.apache.org/projects/flink/flink-docs-release-1.0/apis/streaming/fault_tolerance.html
  - Changing how state is stored internally (via state backends):
https://ci.apache.org/projects/flink/flink-docs-release-1.0/apis/streaming/state_backends.html
