HBase Architecture And Data Model - Quick And Easy …
WebOct 13, 2024 · HBase is an open-source, distributed, scalable, and NoSQL database written in Java. HBase runs on top of the Hadoop Distributed File System and provides random read and write access. It is a data model similar to Google’s big table designed to provide fast random access to huge volumes of structured data. WebHBase is designed for Key-Value workloads with random read and write access patterns. HBase is a sparse, distributed, persistent multidimensional sorted map. The map is indexed by a row key, column key, and a timestamp; each value in the map is an uninterpreted array of bytes. Applications store rows in labelled tables. As we know, HBase is a column-oriented NoSQL database. Although it looks similar to a relational database which contains rows and columns, but it is not a relational database. Relational databases are row oriented while HBase is column-oriented.
