Subject [jira] [Commented] (HBASE-15539) HBase Client region location is expensive
Date Sat, 26 Mar 2016 20:20:25 GMT

    [ https://issues.apache.org/jira/browse/HBASE-15539?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15213186#comment-15213186
] 

Vladimir Rodionov commented on HBASE-15539:
-------------------------------------------

I load 1B small rows (rowkey=16 byte, value = 8 bytes) using BufferedMutator with batch size
1000. Table has 1 CF, only one region, splits are disabled. Compaction is on, but maximum
selection size is limited to 1GB. Test runs locally on my laptop (MBP, fast SSD).
