Rong Rong created FLINK-15475: --------------------------------- Summary: Add isOutputTypeUsed() API to Transformation Key: FLINK-15475 URL: https://issues.apache.org/jira/browse/FLINK-15475 Project: Flink Issue Type: Improvement Components: API / Core, API / DataSet, API / DataStream Reporter: Rong Rong Assignee: Rong Rong
Currently there's no way to "peek" into a Transformation and see if OutputType has been used or not. The only way is to invoke the {{setOutputType}} API and wrap around it with a try-catch block. It would be nice if we have a `isTypeUsed()` or `isOutputTypeUsed()` API to check whether a particular transformation has a definitive output type set / used or not. -- This message was sent by Atlassian Jira (v8.3.4#803005)
