Stephan Ewen reassigned FLINK-3370: ----------------------------------- Assignee: (was: Stephan Ewen) > Add an aligned version of the window operator > --------------------------------------------- > > Key: FLINK-3370 > URL: https://issues.apache.org/jira/browse/FLINK-3370 > Project: Flink > Issue Type: Improvement > Components: API / DataStream > Affects Versions: 1.0.0 > Reporter: Stephan Ewen > Priority: Major > Labels: stale-assigned > > The windowing operators currently follow a generic implementation for support > of unaligned windows. > We can gain efficiency by creating a variant that is optimized for aligned > windows: > - Aligned windows can use aligned triggers, which keep no per-key state > - Less trigger state means less checkpointing data > - Based on the aligned windows, we can create sliding event time windows > that do not replicate data into the different overlapping windows -- This message was sent by Atlassian Jira (v8.3.4#803005)
