Stephan Ewen created FLINK-3370: ----------------------------------- Summary: 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: Windowing Operators Affects Versions: 1.0.0 Reporter: Stephan Ewen
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 (v6.3.4#6332)
