One of the exciting features coming in Cassandra 4.0 is the addition of Virtual Tables. They will expose elements like configuration settings, metrics, or running compactions through the CQL interface instead of JMX for more convenient access. This post explains what Virtual Tables are and walks through the various types that will be available in version 4.0.
Did you ever wonder how to change the hardware efficiently on your Apache Cassandra cluster? Or did you maybe read this blog post from Anthony last week about how to set up a balanced cluster, found it as exciting as we do, but are still unsure how to change the number of vnodes?
Apache Cassandra is fantastic for storing large amounts of data and being flexible enough to scale out as the data grows. This is all fun and games until the data that is distributed in the cluster becomes unbalanced. In this post we will go through how to set up a cluster with predictive token allocation using the
allocate_tokens_for_keyspace setting, which will help to evenly distribute the data as it grows.
