HBase data model part 1


It is very important to understand the data model of HBase and the core principle on which it stands and provides the foundation to scale. We will go through the following concepts:

  • Logical view

  • Physical view

  • Tables

  • Namespace

  • Rows

  • Columns

  • Column families

  • Column qualifier

  • Cells

Logical view of HBase represents distributed, persistent multinational store map, which represents the data in a column and row, key along a timestamp. It also shows a representation of how data is kept to get maximum scalability and performance.

The following screenshot shows data that is represented in an HBase table:

The logical representation of the preceding table is as follows:
