- Log-structured storage
- CQL (Cassandra Structure Language)
- Ease of installation
- The node setup
This product is used as the storage facility for a very-high-throughput application, where a lot of NoSQL data is being captured and it needs to be processed.
The clustering needs to be better; it is getting there.
I have used it for four years.
Cassandra is stable thus far; the problems that I have encountered were with CQL and the JSON support in CQL.
The scalability is good, as long as you understand how to set up the nodes.
I did not have any interactions with technical support, because I was able to find answers to my questions online as I did my searches.
The other solutions that I have used have been the SQL engines but for this project, Cassandra was determined to be the better solution.
Setup was very straightforward.
Pricing and licensing depends on what you are doing: If you are using it for major production work, I recommend that you purchase the level of support that you would need.
This was the only product that was evaluated.
Learn how many nodes you are going to need and set up the right level of replication.
