Dezhi Cai created FLINK-14001: --------------------------------- Summary: add a API to enable user to get the operator code generated by Flink engine Key: FLINK-14001 URL: https://issues.apache.org/jira/browse/FLINK-14001 Project: Flink Issue Type: Wish Components: Runtime / Task Affects Versions: 1.9.0 Reporter: Dezhi Cai Fix For: 1.9.1
In Spark, we can invoke Dataset method "queryExecution.debug.codegen()" to get the code produced by Catalyst. If we add a similar API to enable user to get the code generated by Flink engine, this would be a very nice way to provide more verbose feedback for debugging. reference link : [https://medium.com/virtuslab/spark-sql-under-the-hood-part-i-26077f85ebf0] -- This message was sent by Atlassian Jira (v8.3.2#803003)
