Wellington Chevreuil resolved HBASE-27997. ------------------------------------------ Resolution: Done > 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 > Affects Versions: 2.6.0, 3.0.0-alpha-4 > 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. 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. -- This message was sent by Atlassian Jira (v8.20.10#820010)
