Subject [jira] [Commented] (CASSANDRA-14618) Create fqltool replay command
Date Wed, 29 Aug 2018 08:57:00 GMT


Marcus Eriksson commented on CASSANDRA-14618:

bq. This patch depends directly on the DataStax driver. 
yeah lets move it to tools/ (I'll do that once review is done as it might mess up the PR)

bq. Something like version "0" was the first version (pre-4.0)
Since full querylogging has not been shipped in a released version, maybe we can punt the
versioning until after that? Ie, whatever we release in 4.0 is version 0, then we add versioning

> Make it possible to replay the full query logs from CASSANDRA-13983 against one or several
clusters. The goal is to be able to compare different runs of production traffic against different
versions/configurations of Cassandra.

by the timestamps recorded
