Subject Commitlog questions
Date Wed, 09 Apr 2014 10:06:52 GMT

1)      Why is the default 4GB?  Has anyone changed this? What are some aspects to consider
when determining the commitlog size?

2)      If the commitlog is in periodic mode, there is a property to set a time interval to
flush the incoming mutations to disk.  This implies that there is a queue inside Cassandra
to hold this data in memory until it is flushed.

a.       Is there a name for this queue?

b.      Is there a limit for this queue?

c.       Are there any tuning parameters for this queue?
