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.

> 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.
