Subject [jira] [Commented] (HBASE-3434) ability to increment a counter without reading original value from storage
Date Thu, 24 Mar 2016 19:20:25 GMT

    [ https://issues.apache.org/jira/browse/HBASE-3434?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15210804#comment-15210804

Jean-Marc Spaggiari commented on HBASE-3434:

Let's wait for Paul to ring here but Paul's idea was really accumulation. Like counters, but
not only. Also why not Avro objetc and then you only put the modified fields later and accumulate
on compactions and reads. You can plug any compaction logic you want.

> There are a bunch of applications that do read-modify-write operations on HBase constructs,
e.g  a counter; The counter value has to be read in from hdfs before it can be incremented.
 We have an application where the number of increments on a counter far outnumbers the number
of times the counter is used or read. For these type of applications, it will be very beneficial
to not have to read in the counter from disk before it can be incremented.
