ASF GitHub Bot commented on FLINK-3296: --------------------------------------- Github user StephanEwen commented on the pull request: https://github.com/apache/flink/pull/1563#issuecomment-178020653 Code looks good. I would like to update the docs to include a bit more info (like in the inline comment) and at least refer to the `addSink(...)` method, for fault tolerant sinks. > DataStream.write*() methods are not flushing properly > ----------------------------------------------------- > > Key: FLINK-3296 > URL: https://issues.apache.org/jira/browse/FLINK-3296 > Project: Flink > Issue Type: Bug > Components: Streaming Connectors > Reporter: Robert Metzger > Assignee: Robert Metzger > Priority: Critical > > The DataStream.write() methods rely on the {{FileSinkFunctionByMillis}} > class, which has a logic for flushing records, even though the underlying > stream is never flushed. This is misleading for users as files are not > written as they would expect it. > The code was initial written with FileOutputFormats in mind, but the types > were not set correctly. This PR opened the write() method to any output > format: https://github.com/apache/flink/pull/706/files -- This message was sent by Atlassian JIRA (v6.3.4#6332)
