Yi Deng updated HBASE-12338: ---------------------------- Status: Patch Available (was: Open) > Client side scanning prefetching. > --------------------------------- > > Key: HBASE-12338 > URL: https://issues.apache.org/jira/browse/HBASE-12338 > Project: HBase > Issue Type: Sub-task > Components: Client > Affects Versions: 0.98.6.1, 1.0.0, 2.0.0 > Reporter: Yi Deng > Assignee: Yi Deng > Labels: prefetch, results, scanner > Attachments: > 0001-Add-ScanPrefetcher-for-client-side-scanning-prefetch.patch, > 0001-ScanPrefetcher.patch, > 2.0-0001-Add-ScanPrefetcher-for-client-side-scanning-prefetch.patch, > 2.0-0002-Add-ScanPrefetcher-for-client-side-scanning-prefetch.patch, > 2.0-0003-Add-ScanPrefetcher-for-client-side-scanning-prefetch.patch > > > Since server side prefetching was not proved to be a good way to prefetch, we > need to do it on client side. > This is a wrapper class that takes any instance of `ResultScanner` as the > underneath scanning component. The class will schedule the scanning in a > background thread. There is a buffering queue storing prefetched results, > whose's length is configurable. The prefetcher will release the thread if the > queue is full and wait for results to be consumed. -- This message was sent by Atlassian JIRA (v6.3.4#6332)
