What is a key capability of Apache HBase?

• A. Only supports structured data
• B. Offers automatic failover support
• C. Does not allow scalability
• D. Provides data in fixed-size blocks

Answer: (B)

Apache HBase is designed to handle large volumes of data in a distributed environment, and one of its critical features is its support for automatic failover. This capability ensures that if a master node fails, the system can continue to operate by automatically switching to a standby master. This resiliency is crucial for maintaining high availability in big data applications where downtime can lead to significant service interruptions and data loss. The ability to support seamless failover allows organizations to build reliable systems that can manage data across multiple nodes, ensuring that applications using HBase remain operational even during hardware failures or maintenance activities. This high availability feature is fundamental in environments that require continuous access to data and service reliability. Apache HBase excels in handling unstructured and semi-structured data, offering immense scalability, and managing data dynamically rather than in fixed-size blocks, which aligns with its use case as a NoSQL datastore.
