Subject [jira] [Commented] (CASSANDRA-8929) Workload sampling
Date Sun, 30 Aug 2015 05:44:46 GMT

    [ https://issues.apache.org/jira/browse/CASSANDRA-8929?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14721400#comment-14721400

sankalp kohli commented on CASSANDRA-8929:
------------------------------------------

We are also looking at doing something very similar so this feature will be of great help.
It will be a good start to to record the traffic but we should also try to find a way to find
something about the existing data. A simple select statement on a small CQL partition will
be very different from the one on large CQL partition in terms of load on C*. 

We should try to find a way to deal with this as well ideally.... may be as a different JIRA.
(I am not sure if someone also mentioned this before in the comments)

> Workload *recording* looks to be unworkable (CASSANDRA-6572).  We could build something
almost as useful by sampling the requests sent to a node and building a synthetic workload
with the same characteristics using the same (or anonymized) schema.
