Subject [jira] [Commented] (HBASE-11737) Document callQueue improvements from HBASE-11355 and HBASE-11724

    [ https://issues.apache.org/jira/browse/HBASE-11737?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14102952#comment-14102952

Matteo Bertozzi commented on HBASE-11737:
-----------------------------------------

{quote}
hbase.ipc.server.callqueue.read.ratio
This factor weights the queues toward reads (if below .5) or writes (if above .5).
{quote}
Other way around, the examples are ok except one.

{quote}
A value of .6 uses 75% of the queues for writing and 25% for reading. Given a value of 10
for
hbase.ipc.server.num.callqueue, 7 queues would be used for reads and 3 for writes.</para>
{quote}
some weird math in here. 0.6 should give you 60% and not 75% it is basically the reverse of
the 0.3 example above which is good. and it is also 60% of reading (only the first part is
wrong)

{quote}
You can also split the read queues so that separate queues are used for short reads
(from Get operations) and short reads (from Scan operations)
{quote}
short read (get) and long reads (scan) you have two "short" in there.
