I was surveying middleware to build a home automation, and I came across Kaa.
I noticed that one of Kaa supported NoSQL database option is Cassandra, and I would like to understand more about its deployment scenario in cluster mode.
- I followed the installation guide on official link to build a standalone Kaa node with a Cassandra installed on the same node. However, my question would be that is there a way to have a external Cassandra cluster served as a separate storage node? I do not see there is an option in etc configuration file.
- What is the default RF for storing large amount of endpoints, and what is the CL for read / write operation if using Cassandra as storage engine.
Thanks.
You can configure Cassandra cluster on separate nodes, use new Cluster-setup documentation for details.
RF and CL value you can choose based on Cassandra documentation. For example Data distribution and replication.
