Subject [jira] [Commented] (CASSANDRA-13614) Batchlog replay throttle should be dynamically configurable with jmx and possibly nodetool
Date Thu, 29 Jun 2017 00:21:00 GMT

    [ https://issues.apache.org/jira/browse/CASSANDRA-13614?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16067500#comment-16067500

Paulo Motta commented on CASSANDRA-13614:
-----------------------------------------

Sorry for the delay, the latest changes look good! Just one minor nitpick: even though we
have {{nodetool sethintedhandoffthrottlekb}}, the original convention was to not to have units
on the nodetool command names ({{get/setcompactionthroughput}}, {{get/setstreamthroughput}},
{{getmaxhintwindow}}) etc, so in order to have some consistency (except for {{sethintedhandoffthrottlekb}},
which we can probably change later), I think it's better to keep the command name {{get/setbatchlogreplaythrottle}},
WDYT? Sorry for not having pointed out this before.

> As it is said in [CASSANDRA-13162|https://issues.apache.org/jira/browse/CASSANDRA-13162],
batchlog replay can be excessively throttled with materialized views. The throttle is controlled
by the property {{batchlog_replay_throttle_in_kb}}, which is set by default to (only) 1024KB,
and it can't be configured dynamically. It would be useful to be able of modifying it dynamically
with JMX and possibly nodetool.
