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 reliability?
All three databases are designed for high availability and resilient to failure. However, Cassandra has a reputation for being particularly reliable in distributed environments thanks to its architecture based on the Amazon Dynamo paper. MongoDB and Couchbase are also reliable and have advanced capabilities for replication and failover.
