------------------------------------------------
Summary: Persist list of Hfiles names for which prefetch is done
Key: HBASE-27313
URL: https://issues.apache.org/jira/browse/HBASE-27313
Project: HBase
Issue Type: Improvement
Components: BucketCache
Reporter: Shanmukha Haripriya Kota
Persist list of Hfiles names for which prefetch is completed when persist for
in-memory bucket cache mapping state is enabled.
We need to persist the Set, which contains a list of all the HFiles for which
the prefetch has completed along with the In-memory state of the bucket cache
so that when we restart and if any prefetch is scheduled again for the same
HFile and we already have the in-memory state retrieved, we can skip the
prefetch for it.
