Rishit Shroff reassigned HBASE-7408: ------------------------------------ Assignee: Rishit Shroff > Make compaction to use pread instead of sequential read > ------------------------------------------------------- > > Key: HBASE-7408 > URL: https://issues.apache.org/jira/browse/HBASE-7408 > Project: HBase > Issue Type: Improvement > Reporter: Rishit Shroff > Assignee: Rishit Shroff > Priority: Minor > Original Estimate: 24h > Remaining Estimate: 24h > > As we discovered lately, HFile compactions use sequential reads to fetch > blocks. It cause unwanted streaming of data from HDFS to region servers when > there is a cache hit. Lets change to use preads to reduce iops on disks. -- This message was sent by Atlassian JIRA (v6.1.5#6160)
