[ https://issues.apache.org/jira/browse/HBASE-27997?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ] Rahul Agarkar updated HBASE-27997: -- Description: HBASE-27313 implemented the prefetch persistence feature where it persists the list of hFiles prefetched in the bucket cache. This information is used to reconstruct the cache in the event of a server restart/crash. Currently, only the list of hFiles is persisted. However, for the new PrefetchAwareLoadBalancer (work in progress) to work, we need the information about how much a region is prefetched on a region server. This Jira introduces an additional map in the prefetch executor to maintain the information about how much a region has been prefetched on that region server. The size of region server prefetched is calculated as the total size of all hFiles prefetched for that region. > Enhance prefetch executor to record region prefetch information along with > the list of hfiles prefetched > > > Key: HBASE-27997 > URL: https://issues.apache.org/jira/browse/HBASE-27997 > Project: HBase > Issue Type: Sub-task > Components: BucketCache >Reporter: Rahul Agarkar >Assignee: Rahul Agarkar >Priority: Major > > HBASE-27313 implemented the prefetch persistence feature where it persists > the list of hFiles prefetched in the bucket cache.
