Rex Remind commented on FLINK-8236:
-----------------------------------
Hello,
I would like to set parallelism on one of my table operations. This ticket
suggests this still isn't possible. Has there been any progress on this?
Thanks
> Allow to set the parallelism of table queries

> Key: FLINK-8236
> URL: https://issues.apache.org/jira/browse/FLINK-8236
> Project: Flink
> Issue Type: Improvement
> Components: Table SQL / API
> Affects Versions: 1.4.0
> Reporter: Timo Walther
> Assignee: Xingcan Cui
> Priority: Major
>
> Right now the parallelism of a table program is determined by the parallelism
> of the stream/batch environment. E.g., by default, tumbling window operators
> use the default parallelism of the environment. Simple project and select
> operations have the same parallelism as the inputs they are applied on.
> While we cannot change forwarding operations because this would change the
> results when using retractions, it should be possible to change the
> parallelism for operators after shuffling operations.
> It should be possible to specify the default parallelism of a table program
> in the {{TableConfig}} and/or {{QueryConfig}}. The configuration per query
> has higher precedence that the configuration per table environment.
