How does Apache HBase work?

What is Apache HBase used for?

Apache HBase is used to have random, real-time read/write access to Big Data. It hosts very large tables on top of clusters of commodity hardware. Apache HBase is a non-relational database modeled after Google’s Bigtable. Bigtable acts up on Google File System, likewise Apache HBase works on top of Hadoop and HDFS.

How is data stored in HBase?

There are no data types in HBase; data is stored as byte arrays in the cells of HBase table. The content or the value in cell is versioned by the timestamp when the value is stored in the cell. So each cell of an HBase table may contain multiple versions of data.

Is HBase a database?

HBase is a column-oriented non-relational database management system that runs on top of Hadoop Distributed File System (HDFS). HBase provides a fault-tolerant way of storing sparse data sets, which are common in many big data use cases.

What are the components of Apache HBase?

The HBase architecture comprises three major components, HMaster, Region Server, and ZooKeeper.

Is HBase easy to use?

Apache HBase has a completely distributed architecture. It can easily work on extremely large scale data. HBase offers high security and easy management which results in unprecedented high write throughput. For both structured and semi-structured data types we can use it.
