Apache HBase

HBase is the Hadoop database. It is a distributed, scalable, big data store. It provides random, real-time read/write access to your Big Data.

When to Use

• Hadoop Ecosystem: Deep integration with HDFS, Hive, Spark.
• Petabyte Scale: Serving billions of rows with low latency.
• Random Access: When you need random R/W on HDFS data (which is usually WORM - Write Once Read Many).

Quick Start

Uses Java API or Shell.
