How to Choose Between HBase and Cassandra

It is recommended to use NoSQL databases when working with Big Data due to their design for fast processing of large data sets and variable, unstructured data. Trying to employ a relational database for Big Data is likely to demonstrate its limitations.

Once you have selected a type of database for your project, you must now decide which database to use. There are several NoSQL databases available, such as MongoDB, RavenDB, Redis, CouchBase, IBM Cloudant, and Amazon DynamoDB, which can all manage the workload.

The Apache Project supports two further NoSQL databases, HBase and Cassandra, which may appear similar at first glance, however upon closer examination, their differences become apparent. To ascertain which of these databases is more suitable for your business, let us compare and contrast Cassandra and HBase.

HBase is described.

Apache HBase, an open-source NoSQL database, is an ideal solution for distributed databases that need to manage large amounts of data. This NoSQL database has the capability to store petabytes of data, and it allows for ad hoc, consistent and real-time access to this data.

HBase utilizes columnar storage, with row keys providing indexing. Through distributing data and queries across a cluster of computers, responses can be delivered in rapid time (often in milliseconds). This makes HBase an ideal choice for very large data repositories, enabling quick retrieval of both row and column data.

HBase offers a non-relational data storage solution, accessible via its Application Programming Interface. For added convenience, HBase and Apache Phoenix can be used together to provide a SQL-based interface. This allows administrators to use familiar SQL syntax when entering, deleting and querying data.

HBase is quick, dependable, and expandable.

Structure of HBase

The building blocks of HBase are as follows:

  • Hmaster
  • Hregionmaster
  • Hregions
  • Zookeeper
  • HDFS

Just who or what is this Cassandra character?

Apache Cassandra is a popular open-source NoSQL distributed database, capable of storing large volumes of data. It is a masterless design, meaning that all nodes offer the same functionality within the cluster, and is suitable for use in both public and private cloud environments, providing assurance of no data loss in the event of a data center failure.

Cassandra is highly sought after for its scalability, high availability and performance, making it a popular choice in the database world. It can be deployed across commodity hardware and cloud infrastructure, making it an ideal choice for mission-critical data. If speed is a necessity, Cassandra is one of the fastest NoSQL databases available and may be the best solution for your company or project.

Cassandra’s Parts

These are the parts that make up Cassandra:

  • Node
  • Polymerase chain reaction
  • Partitioner
  • SStable
  • Memtable
  • Cluster
  • Accountability Record

Exactly What Are the Distinctive Features of HBase and Cassandra?

Let’s look at two crucial parts of a database, write and read performance, where variations might be more noticeable.

To Learn About the Performance, Read

HBase writes are managed by a single server, whereas Cassandra publishes to multiple servers running various versions of software. HBase data is stored using Hadoop Distributed File System (HDFS), which provides bloom filters and black caches for improved read performance. When accessing data, Cassandra needs to check the partition table first.

Performer Writing

In this situation, HBase does not support simultaneous writing, however, Cassandra has the advantage of being able to update both its log and cache concurrently. Furthermore, Cassandra’s consistent hashing allows data to be split and distributed quickly, making writes even faster. In comparison, HBase requires a client to contact the metadata server via Zookeeper to find the location of the address store and table where updates will be made, which creates an extra layer of overhead, thus making HBase writes slower than Cassandra writes.


An increase in random reads and updates on HBase is likely to result in a decrease in average latency. Conversely, as the number of I/O operations in Cassandra grows, latency is seen to increase. However, after 10,000 reads and writes, latency has been observed to decrease.


HBase exhibits a consistent throughput of between 100,000-200,000 operations, with the potential to reach up to 250,000 or more. However, as the volume of reads and writes to Cassandra increases, throughput is seen to rise accordingly.

Take a Look at the Book Latency

HBase has a greater average read latency than other databases, however this delay does not change significantly with the amount of read operations.

To What Extent Does Each Meet Your Needs?

When evaluating this decision, it is important to consider the fault tolerance of the respective databases. In the case of HBase, if the master node fails, the entire database becomes inaccessible. Conversely, Cassandra has a masterless design, meaning it will remain operational even if a node fails; however, discrepancies in data may occur.

HBase is the ideal choice if data consistency is a priority, while Cassandra is the best solution if availability is paramount.
