Apache HBase

Apache HBase is a distributed, scalable, big data store designed to handle massive tables with billions of rows and millions of columns. It's built on top of HDFS (Hadoop Distributed File System) and provides real-time read/write access to your data.

Key Features

• Distributed Architecture:

  • ZooKeeper quorum for coordination

• Data Model:

  • Column-oriented storage
  • Schema-flexible tables
  • Versioned data cells
  • Sparse data handling
  • Row-level atomicity

• Performance:

  • In-memory operation
  • Block cache for hot data
  • Bloom filters for queries
  • Compaction for storage optimization
  • Write-ahead logging
