Performance on updation.

[Ranjini Rathinam <ra...@gmail.com>]

Hi,


I want to know the performance of hbase on doing updation operation.

How good is Hbase on Updation ?

Please suggest.


Thanks in advance.

Which hbase release are you considering ?

Different releases have different implementation for the write path. E.g., 0.98 release has HBASE-8755. In trunk, disruptor is introduced. 
This means write performance gets faster with each major release. 

Cheers

Regardless of what version of hbase you use, updates are initially just as
expensive as new writes.  Newer versions of hbase have become more
efficient at writes.  Updates that require reading the value before an
update (like an append or insert) cost more because of the read operation.

Numbers depend on the size of the data and rowkeys you are using, so we'd
need more details to address the question.
