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?
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.
