CASSANDRA DATABASE INSTALL

You'll see how as we discuss other features in ensuing sections. In fact, Cassandra thrives on this node-based topology. This way, you get more storage options and increased availability over your desired access points.

CASSANDRA DATABASE INSTALL

It's advisable to install Cassandra instances on multiple machines to create a network of nodes.

This means every time you insert data into a MongoDB instance, a (JSON-type) document with the values and their metadata is generated. MongoDB takes the NoSQL concept a step further by being document-based. With Cassandra, your data is stored in non-relational partitions just as you insert them-much like any other NoSQL platform would. To start with, both database solutions are distributed by design. Cassandra has always been free, and it's now managed by the Apache foundation. The developers named Cassandra after a Trojan priestess cursed to speak true prophecies. The platform has always been free, but certain features and dedicated instances attract a subscription fee to the team supporting the platform.Ĭassandra was created at Facebook's HQ in Menlo Park, California, in 2008, for use in Facebook's messaging search module. This need inspired them to create MongoDB. The privately owned marketing company was running thousands of ads concurrently and needed agility and scalability. MongoDB started back in 2007 as an in-house project to handle specific problems faced by DoubleClick. Let's start with a brief history of both platforms, shall we? However, these four factors should give every reader the knowledge necessary to pick Cassandra, MongoDB, or a blend of both. We could go on and on, doing side-by-side contrasts of the features, capabilities, and shortcomings of the two database solutions.

The top use cases for Cassandra and MongoDB.

The robustness of Cassandra compared to MongoDB.

Architectural and handling differences between Cassandra and MongoDB.

Here's what we'll cover in this comparison of Cassandra and MongoDB: Instead, and most importantly, you should know which option works best for explicit use cases. Neither will we limit you to using just one of the two. Quick disclaimer: We're not going to favor either data storage system. This way, you can experience the best in terms of performance, compatibility, and ease of use. Retaining a pragmatic mindset, we'll also help the reader understand how a shrewd analyst/engineer can implement both options.

This post explores the differences you'll encounter when using Cassandra and MongoDB databases. While both systems' approaches to data storage and manipulation lure users in, the actual processes are different enough to polarize their user bases. MongoDB, performance, design, and operational variables top the list of considerations.
