Is Cassandra good or bad?
Cassandra is a
key-value store
for write heavy apps, where storing of hundreds of thousands records per second is needed. It has reliability with cluster auto-healing, by which you can easily take off node in case of cluster failure. It is eventually consistent, well, like other NoSQL databases.
