Congratulations! Very nice work, very interesting features. One question regarding CEP: do you think it's feasible to define pattern over window of 1 month or even more? Is there some deep explanation regarding how this partial states are saved? I mean events that create "funnel" might be separated by very large periods of inactivity/noise On 8 March 2016 at 17:17, Kostas Tzoumas <[hidden email]> wrote:

Great to have this out!
@Radu: You may use this LinkedIn post: https://www.linkedin.com/groups/7414853/7414853-6113008761373290497 @Igor: Having a one month window should work fine. The CEP library only keeps track of the current state of the events which enables you to process large amounts of data over long time intervals.

@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 On Tue, Mar 8, 2016 at 8:32 PM, Igor Berman <[hidden email]> wrote:
