Yu Li commented on HBASE-15163:
-------------------------------
bq. readRequestCount and writeRequestCount are both just counters
Yes but they are not histogram, so still have the 'instantaneous rate is
controlled by how long inbetween metrics snapshots' issue, right? And btw all
metrics proposed in this JIRA are counters.
bq. The user has very little control over the batching
Agree, but we could still see whether there're lots of batch request, right?
And we could see how much load is caused by single get/put and how much is
caused by batch, which is not possible based on existing histogram. Not sure
whether I could convince you sir, but it's indeed useful in our scenario. :-)
