Are these tools useful for other components using the same cassandra
instance for their own schemas? For example, can Hawkular Alerting
leverage this to perform updates to its schema?<br class=""></div></div></blockquote><div><br class=""></div></div>Yes, Cassalog can be used in other projects. It is not dependent on Hawkular Metrics in any way. There are things that we discussed and decided in HWKMETRICS-361 in terms of how to manage schema changes across versions. It boils down more to coming up with a process as opposed to a bunch of code changes.</body></html>
