yinhua.dai created FLINK-9565: --------------------------------- 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. cc [~fhueske] -- This message was sent by Atlassian JIRA (v7.6.3#76005)
