Subject [jira] [Commented] (HBASE-15273) Advance Hadoop Architecture (AHA) - Advance HBase (Umbrella) JIRA
Date Mon, 15 Feb 2016 15:38:18 GMT

    [ https://issues.apache.org/jira/browse/HBASE-15273?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15147496#comment-15147496

Dinesh S. Atreya commented on HBASE-15273:

Compactions when absolutely needed can be made transparent (in the background) by use of appropriate
metadata that points to the right set of HFiles that are current while compactions are going
on and update to the latest set of HFiles after compactions complete.

for more details.
> This JIRA is an umbrella (parent/master) JIRA for advancing HBase given https://issues.apache.org/jira/browse/HDFS-9607.
> This JIRA contemplates on enhancing HBase to support HBase updates subsequent to https://issues.apache.org/jira/browse/HDFS-9607.
Following benefits are estimated to accrue in the following dimensions with the addition of
HBase updates 
> * Performance and Efficiency  -- HBase updates will have a direct impact on performance
and efficiency by reducing the number of duplicate data since the existing data can be updated.
> * Availability -- Minimize or eliminate Compactions. When compactions are needed to be
done, they can be done in a transparent manner in the background.
