This series of blog posts will cover how we test Scylla—first of all for stability and correctness, and also to ensure that Scylla keeps Apache Cassandra compatibility constantly as the project proceeds. Software testing is critical, and especially so for a project that needs to achieve compatibility with some previously existing software. This blog series will cover the tests that we put Scylla through.
You can visualize Scylla performance with Tessera and riemann-dash, thanks to collectd support. Scylla can be configured to send data using the collectd protocol, once per second, which makes it easy to keep an eye on the performance of a whole cluster.
