kfaraz opened a new pull request, #20245:
URL: https://github.com/apache/druid/pull/20245
### Description
If a segment becomes unavailable after it has been added to the load queue
of a historical, it might remain stuck in the queue while other segments are
being loaded. Ideally, all unavailable segments should be prioritized.
### Changes
- Simplify book-keeping in `ServerHolder` by getting rid of method
`simplify()` and treat REPLICATE and LOAD actions as distinct
- In `StrategicSegmentAssigner.updateReplicasInTier()`, check if an
unavailable segment needs to be prioritized and change all in-flight REPLICATE
actions on that segment to LOAD.
### Pending
Handle the same change for `updateReplicasInTierPartial`.
