> Key: FLINK-9565
> URL: https://issues.apache.org/jira/browse/FLINK-9565
> Project: Flink
> Issue Type: New Feature
> Components: Table SQL / API
> Affects Versions: 1.4.2
> Reporter: yinhua.dai
> Priority: Minor
> Labels: auto-deprioritized-major, stale-minor
>
> As per
> [https://stackoverflow.com/questions/50790023/does-flink-sql-support-to-run-projections-in-parallel,]
> scalar UDF in the same SQL is always evaluated sequentially even when those
> UDF are irrelevant, it may increase latency when the UDF is time consuming
> function.
> It would be great if Flink SQL can support to run those UDF in parallel to
> reduce calculation latency.
