---------------------------------
Summary: Evaluating scalar UDFs in parallel
Key: FLINK-9565
URL: https://issues.apache.org/jira/browse/FLINK-9565
Project: Flink
Issue Type: New Feature
Components: Table API & SQL
Reporter: yinhua.dai
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 irrelative, 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.
