[jira] [Commented] (FLINK-9407) Support orc rolling sink writer

["Stephan Ewen (JIRA)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/FLINK-9407?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16533040#comment-16533040 ] 

Stephan Ewen commented on FLINK-9407:
-------------------------------------

We have started an effort to completely redesign the BucketingSink. The initial work-in-progress looks quite promising.
It is tracked under FLINK-9749

Please take a look at FLINK-9749 and the subtask FLINK-9753
The description outlines why I believe the simple approach suggested here may not be enough (will frequently result in badly compressed ORC/Parquet).

Please let us know what you think in FLINK-9753

> Currently, we only support {{StringWriter}}, {{SequenceFileWriter}} and {{AvroKeyValueSinkWriter}}. I would suggest add an orc writer for rolling sink.
