What is Cassandra?

Apache Cassandra is an open source, decentralized; highly available, fault-tolerant, distributed, column-oriented, elastically scalable database that bases its distribution design on its data model and Amazon’s Dynamo on Google’s Bigtable.

Cassandra originated at Facebook in 2007 to solve that company’s inbox search problem, in which they had to deal with large volumes of data in a way that was difficult to scale with traditional methods. Specifically, the team had requirements to handle huge volumes of data in the form of message copies, reverse indices of messages, and many random reads and many simultaneous random writes. For developers and administrators coming from the relational world, the Cassandra data model can be very difficult to understand initially. Some terms, such as “keyspace,” are completely new, and some, such as “column,” exist in both worlds but have different meanings. It can also be confusing if you’re trying to sort through the Dynamo or Bigtable source papers, because although Cassandra may be based on them, it has its own model.

Cassandra Overview

Cassandra is a distributed storage system for managing very large amounts of structured data spread out across many commodity servers, while providing highly available service with no single point of failure. Cassandra aims to run on top of an infrastructure of hundreds of nodes (possibly spread across different data centers). At this scale, small and large components fail continuously. The way Cassandra manages the persistent state in the face of these failures drives the reliability and scalability of the software systems relying on this service. While in many ways Cassandra resembles a database and shares many design and implementation strategies therewith, Cassandra does not support a full relational data model; instead, it provides clients with a simple data model that supports dynamic control over data layout and format. Cassandra system was designed to run on cheap commodity hardware and handle high write throughput while not sacrificing read efficiency.

Data Models of Cassandra

Cassandra deals with unstructured data and has flexible schema.

Keyspace is the outermost container that contains data corresponding to an application.

Uses a query-driven approach

A partitioned row store with tunable consistency

A distributed database – Reads/Writes when the data is grouped on nodes by partition.

Cassandra Cluster Topology

Cassandra’s topology relies on a peer-to-peer distributed architecture. All nodes participate in a “ring” or datastore cluster, and communicate with each other via a gossip protocol. Data, depending on the user preference is either orderly or randomly distributed across all nodes.

cassandra cluster topology

Additionally, data replication is available and is highly recommended to the user for fault-tolerance, as it allows for data durability in cases of node failures. The minimum replica set recommended is three. This means that should n nodes be found adequate for a given cluster/workload combination, 3n nodes should be provisioned. The user would then enable Cassandra to replicate each data chunk to three nodes, allowing for any part of database to be accessible even under node failures. For greater fault tolerance, a higher replica set number can be chosen.
