The terms are almost the same, but their meanings are different. Understand Cassandra’s architecture very well and what it does under the hood. For example, there are no foreign key constraints available – it has to be handled by one’s own application. It is a big data analytics system. That can handle real time reads and writes. This is achieved through Cassandra’s Hadoop integration. The sheer amount and velocity of today’s data makes capturing, filtering, storing and analyzing a real challenge. If one is coming from a relational database background with strong ACID semantics, then one must take the time to understand the eventual consistency model. Ltd. All rights Reserved. Understanding one’s use cases and data access patterns clearly before modeling data with Cassandra and to read all the available documentation is a must. Cassandra is a distributed, scalable and secure database built on the principles of the NoSQL storage with no single point of failure assurances. Some of the features of Cassandra data model are as follows: Data in Cassandra is stored as a set of rows that are organized into tables. Talking about Hadoop and Cassandra, they take the data out of Cassandra and put it into Hadoop and run batch and analytics on that, and then that goes back into Cassandra. They are not using the Datastax (official Cassandra Maintainer) Enterprise edition for this integration; just the open source Hadoop installation with Cassandra.
