Dong Lin reassigned FLINK-31240: -------------------------------- Assignee: Yunfeng Zhou (was: Jiang Xin) > Reduce the overhead of conversion between DataStream and Table > -------------------------------------------------------------- > > Key: FLINK-31240 > URL: https://issues.apache.org/jira/browse/FLINK-31240 > Project: Flink > Issue Type: Improvement > Components: Table SQL / API > Reporter: Jiang Xin > Assignee: Yunfeng Zhou > Priority: Major > Labels: pull-request-available > > In some cases, users may need to convert the underlying DataStream to Table > and then convert it back to DataStream(e.g. some Flink ML libraries accept a > Table as input and convert it to DataStream for calculation.). This would > cause unnecessary overhead because of data conversion between the internal > data type and the external data type. > We can reduce the overhead by checking if there are paired > `fromDataStream`/`toDataStream` function call without any transformation, if > so using the source datastream directly. > -- This message was sent by Atlassian Jira (v8.20.10#820010)
