> Recovery of BucketCache and Prefetched data after RS Crash
> ----------------------------------------------------------
>
> Key: HBASE-27686
> URL: https://issues.apache.org/jira/browse/HBASE-27686
> Project: HBase
> Issue Type: Improvement
> Components: BucketCache
> Reporter: Shanmukha Haripriya Kota
> Assignee: Shanmukha Haripriya Kota
> Priority: Major
>
> HBASE-27313 introduced the ability to persist a list of hfiles for which
> prefetch has already been completed, so the we can avoid prefetching those
> files again in the event of a graceful restart, but it doesn't cover crash
> scenarios, as if the RS is killed or abnormally stopped, the list wouldn't be
> saved.
> This change aims to persist the list of already prefetched from a background
> thread that periodically checks cache state and persists the list if updates
> have happened.
