[Hawkular-dev] Hawkular Metrics 0.21.0 - Release

[Thomas Segismont]

Congrats to the team!

With respect to HWKMETRICS-510
<https://issues.jboss.org/browse/HWKMETRICS-510>, how do you make sure that
the server is not overwhelmed with retries stored in memory? Is the client
response sent after the retry?

Thanks

> Hello Everybody,
> I am happy to announce release 0.21.0 of Hawkular Metrics. This release is
> anchored by performance enhancements and general fixes.

> Here is a list of major changes:
>

>    Cassandra
>    - *Cassandra 3.0.9 is now the supported version of Cassandra.*
>       - Note: this is a rollback from previously supported version of 3.7
>       due to Cassandra community recommendations for stability and production
>       deployment. Cassandra 3.7 or 3.9 are still compatible but development and
>       testing use 3.0.9 release.
>    -
>
>    Compression
>    - Fixed an issue that allowed duplicate instances of the compression
