How do I choose between MongoDB and Cassandra?

The database that you should choose depends on your priorities. In terms of availability, Cassandra has the upper hand. It’s highly distributed architecture means you can continue writing to a cluster even when nodes fail. MongoDB, on the other hand, is great for storing unstructured data.

How does Cassandra differ from MongoDB and Neo4j?

It is distributed database management system that is open-source with a wide column store, NoSQL database which is designed to handle and support large amounts of data across many servers….Difference between Neo4j and Cassandra :

What’s the difference between Cassandra and MongoDB databases?

With Cassandra, each master node can accept different writes in parallel. Therefore, the more master nodes you have, the more data you can write at once. If you need to write a lot of data, your allegiance should probably lean towards Cassandra. Although both databases fall within the NoSQL family, NoSQL is a broad category.

What’s the difference between MongoDB and MySQL?

Unlike a typical relational database management system (RDBMS), tables can be created, altered, and dropped while the database is running and processing queries.

What are the disadvantages of using Cassandra in a cluster?

Cassandra isn’t without its disadvantages. As the architecture is distributed, replicas can become inconsistent. If a node in a cluster goes down, its coordinator node tries to preserve the data in the form of hints.
