Re: Cassandra Cluster Expansion Criteria

50% disk free is really only required with STCS (in size tiered compaction, if you have 4 files of a similar size, they'll be joined together - there are theoretically times when all of your data is in 4 files of the same size, and to join them together you'll temporarily double your disk

Re: Cassandra Cluster Expansion Criteria

Hi Asad, First, you need to understand the factors impacting cluster capacity. Some of the important factors to be considered while doing capacity planning of Cassandra are: 1.  Compaction strategy: It impacts disk space requirements and IO/CPU/memory overhead for compactions. 2. Replication

Re: Cassandra Cluster Expansion Criteria

Ideally you should maintain 50% disk space. SLA and Node load is also very important to make the decision. > On Jun 29, 2017, at 6:45 AM, ZAIDI, ASAD A wrote: > > Hello Folks, > > I’m on Cassandra 2.2.8 cluster with 14 nodes , each with around 2TB of data > volume. I’m

Cassandra Cluster Expansion Criteria

Hello Folks, I’m on Cassandra 2.2.8 cluster with 14 nodes , each with around 2TB of data volume. I’m looking for a criteria /or data points that can help me decide when or if I should add more nodes to the cluster and by how many nodes. I’ll really appreciate if you guys can share your
