[jira] [Commented] (CASSANDRA-8929) Workload sampling

    [ https://issues.apache.org/jira/browse/CASSANDRA-8929?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14350771#comment-14350771 ] 

Benedict commented on CASSANDRA-8929:
-------------------------------------

I'm not sure server-side workload recording or sampling is likely to ever be _that_ useful, since the data dependencies are lost. What's the specific goal here?

> 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.
