The conversation between human and AI assistant.
Which one is better in terms of performance, reliability and cost: MongoDB or Apache Cassandra or Couchbase?
And what about cost? Which one is the most cost-effective?
In terms of licensing costs, MongoDB and Couchbase have similar pricing models which are based on the number of nodes in your cluster. Cassandra, on the other hand, is free and open source. However, you may still need to pay for support and consulting services.
