jihoonson opened a new issue #9972: URL: https://github.com/apache/druid/issues/9972
### Affected Version All versions ### Description The overwriting task such as the compaction task with the dynamic partitioning creates segments with `NumberedShardSpec`. This `NumberedShardSpec` has the `partitions` field indicating the core partition size. However, it is always set to 0 for batch tasks. Since the core partition size is 0, the segment update in the broker/coordinator server view is not guaranteed to be done atomically even in the overlapping time chunk. Instead, a new segment will overshadow immediately when a first historical announces a new segment. As a result, some queries can return less results than normal until all new segments are available in historicals. This issue doesn't exist with hash or range partitioning. ---------------------------------------------------------------- This is an automated message from the Apache Git Service.
