In the era of big data analytics and data science, the modern-day solution to handling and managing distributed databases is NoSQL databases. The salient features that NoSQL offers are the need of the hour. Some of the significant reasons NoSQL is most recommended are the ability to manage large volumes of data, speed, easy scalability, fail-over safety, great CPU and memory competencies, faster performance, and no database breakage. And, as we talk about NoSQL databases, the two reigning technologies are HBase vs Cassandra which are constantly being compared.

Both are parented by Apache and hence hold many similarities. Developers are sometimes unable to mark the difference between HBase and Cassandra. But they do have their own individualistic characteristics, which sets them apart. Before we delve deeper into the comparison between the two, let us have a look at them individually.

What Is HBase?

HBase is an open-source non-relational distributed database modeled after Google’s Bigtable and written in Java – Wikipedia

Apache HBase is best used when there is a requirement for random and real-time read/write access to Big Data databases and huge amounts of structured data. It offers Bigtable-like competencies on the top of HDFS and Hadoop – compression, in-memory operation, and Bloom filters being some of them. HBase is a scalable, column-dependent database for structured data that facilitates effective and accurate management of huge sets of data that are spread out amidst several servers. It offers data replication and the three major components of HBase are Zookeeper, Region Server, and HMaster.

HBase is built on Java and hence offers great support for APIs like REST, Scala, Jython, etc. It has a standalone versioned database that is utilized in the development scenario. It is mainly designed to handle real-time queries in huge tables that have multiple rows and columns and execute across a cluster of hardware. It executes on a four-dimensional data model and possesses scalability and fault tolerance.

Features Of HBase:
  • Consistency in reads and writes
  • Support to export metrics through the Hadoop metrics subsystem
  • Automated failover support and sharding of tables
  • Linear scalability and modularity
  • Easily usable Java API for clients
  • Data storage as key or values
  • Best suited for range-based scan
Companies Using HBase:
  • Tumblr
  • Hubspot
  • Vinted
  • Pinterest
  • JVM Stack
  • Adobe
  • Flurry
  • Celer Technologies
  • Yahoo!
  • Lorven Technologies
  • Zendesk Inc
  • ResearchGate

What Is Cassandra (Apache Cassandra)?

Cassandra is a free and open-source, distributed, wide-column store, NoSQL database management system designed to handle large amounts of data across many commodity servers, providing high availability with no single point of failure – Wikipedia

Powered by Apache, Cassandra is a NoSQL database that can easily manage huge amounts of data in a quick manner hence it is popular among many organizations globally, for its accessibility, performance, and linear scalability. It has proven fault tolerance on cloud-based infrastructure or commodity hardware and proves best for mission-critical information. It can bear data center outages without facing any loss because of its replication across multiple data centers and low latency.

Since it has effective architectural choices, it has an edge over the rest for real-time applications. It is ideal for applications where data loss is not affordable and there are no network hassles. It is easy to add new machines with no downtime hassle since there is a linear increase in the read/write throughput. Cassandra can stream data within nodes while scaling processes are going on, making it a faster and more elastic environment.

Apache Cassandra Features:
  • Low latency and masterless architecture
  • Scalable, testable on multiple clusters
  • High-end security and observability
  • Zero Copy Streaming
  • Works with a wide column store
  • Fast performance reads/writes
  • No multiple secondary indexes needed
Companies Using Cassandra:
  • Facebook
  • Instagram
  • Uber
  • Reddit
  • Accenture
  • Netflix
  • Spotify
  • Instacart
  • Twitter
  • Apple
  • eBay
  • Zalando
  • Avito
