[jira] [Resolved] (FLINK-2680) Create a dedicated aligned-event time window operator

     [ https://issues.apache.org/jira/browse/FLINK-2680?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]

Stephan Ewen resolved FLINK-2680.
---------------------------------
    Resolution: Won't Fix

Rather, we should unify the processing and event time windows and make only distinctions on aligned/unaligned triggering behavior.

> Aligned event time windows (where every key triggers and evicts in the same way) are the most common case, and should have a dedicated high-performance implementation that supports:
>   - pre-aggregated state
>   - non aggregated state
