Cassandra Overview

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. It is capable enough to store hundreds of terabytes of data. 

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 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 Cassandra cluster can possess one or more analogous keyspaces.
  • A partitioned row store with tunable consistency.
  • Efficient enough to diagnose and resolve many common production problems.
  • 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. It comprises of number of Cassandra nodes where data is written. All nodes participate in a “ring” or datastore cluster, and communicate with each other via a gossip protocol. Each node must be configured aptly before beginning a cluster. Data, depending on the user preference is either orderly or randomly distributed across all nodes.

cassandra cluster topology

During configuration, Cassandra Cluster topology consists of either adding or removing the Cassandra nodes within the cluster. 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 addition and elimination of replica count can be handled according to the requirements. The minimum replica set recommended is three. This means that should have 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.
