[GitHub] [druid] jihoonson opened a new issue #9973: Overwriting tasks doesn't guarantee atomic update of segments across time chunks
jihoonson opened a new issue #9973:
URL: https://github.com/apache/druid/issues/9973
### Affected Version
All versions
### Description
The timeline currently doesn't guarantee that all segments of an overwriting task will replace all old segments atomically. This can lead to the inconsistency in the query result; a query can read mixed versions of segments per time chunk.

I agree. It's an improvement rather than a bug.

Hi @jihoonson, would you kindly also tag a `Improvement` label here? Because I used to tell my users that this is not a bug but a feature of Druid that promises `eventual consistency` about the state transformation.
