Andrew Purtell resolved HBASE-2362. ----------------------------------- Resolution: Not a Problem Reopen or file new issue if relevant for modern HBase versions > Improve gets/scans when all columns of a key is requested. > ---------------------------------------------------------- > > Key: HBASE-2362 > URL: https://issues.apache.org/jira/browse/HBASE-2362 > Project: HBase > Issue Type: Improvement > Components: regionserver > Reporter: Karthik Ranganathan > > Right now, we get one KeyValue at a time and run it through the matcher even > if the query is to fetch the entire row (or even an entire column family for > a key). This causes the blocks to be fetched serially from HDFS. We can > optimize this by looking at the block map, and fetching all the blocks > spanned by the key in one request to HDFS. -- This message was sent by Atlassian JIRA (v6.2#6252)
