Subject Counters implementation
Date Tue, 13 Nov 2012 00:21:49 GMT

Can anyone reference me to an article/blog detailing how Counters are implemented in HBase?

We get very low throughput of batch of Increment relative to batch of Put, and I would like
to investigate why, by understanding the basic workflow on updating a counter - does it use
block-cache? Does it access disk (IO) on each Increment (to read latest value) ?
