kaka11chen opened a new pull request, #33245:
URL: https://github.com/apache/doris/pull/33245
## Proposed changes
Issue Number: #31442
- Add hive-writer runtime profiles.
- Change output file names to
`${query_id}${uuid}-${index}.${compression}.${format}`. e.g.
`"d8735c6fa444a6d-acd392981e510c2b_34fbdcbb-b2e1-4f2c-b68c-a384238954a9-0.snappy.parquet"`.
For the same partition writer, when the file size exceeds
`hive_sink_max_file_size`, the currently written file will be closed and a new
file will be generated, in which ${index} in the new file name will be
incremented, while the rest will be the same .
- Add `hive_sink_max_open_partitions` to control max open partitions in hive
sink.
