What is most valuable?

I really appreciate the high availability, automated replication, linear scalability, and automated region fail-over.

How has it helped my organization?

What do you think of Cassandra?

Valuable Features Log-structured storage CQL (Cassandra Structure Language) Ease of installation The node setup • Improvements to My Organization 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. • Room for Improvement The clustering needs to be better; it is getting there. • Use of Solution I have used it for four years. • Stability Issues Cassandra is stable thus far; the problems that I have encountered were with CQL and the JSON support in CQL. • Scalability Issues The scalability is good, as long as you understand how to set up the nodes. • Customer Service and Technical Support I did not have any interactions with technical support, because I...

New version from Cassandra 3.5.x onwards this issue got resolved. We are free to stop and start any nodes without any issues. • Stability Issues: no • Scalability Issues: no • Previous Solutions: The earlier solution...

HA is one of the great features of Cassandra with no downtime, e.g., you can achieve continuous data without a single downtime because of node to node ring architecture. • Room for Improvement Maybe they can improve their performance in data fetching from a high volume of data sets.  • Use of Solution One to three years. • Other Solutions Considered ...
