Flink Jira Bot updated FLINK-7193:
----------------------------------
Labels: stale-major (was: )
> Update all OVER window ProcessFunction implementations to use SortedQueueState
> ------------------------------------------------------------------------------
>
> Key: FLINK-7193
> URL: https://issues.apache.org/jira/browse/FLINK-7193
> Project: Flink
> Issue Type: Improvement
> Components: Table SQL / API
> Affects Versions: 1.3.1, 1.4.0
> Reporter: Fabian Hueske
> Priority: Major
> Labels: stale-major
>
> Most OVER windows are implemented as {{ProcessFunction}} with {{MapState}}
> which is keyed on a timestamp. The algorithms are implemented in a way that
> they can leverage a sorted traversal over the timestamp keys but fall back to
> sorting if the traversed keys are not sorted.
> The {{RocksDBStateBackend}} provides sorted iterators.
> FLINK-6219 proposes a {{SortedQueueState}} that guarantees that values can be
> read from a sorted list. Once FLINK-6219 is resolved an a
> {{SortedQueueState}} is available, the OVER window implementations should be
> updated to use the new state type instead of {{MapState}}.
