Answer 1

HBase has advantages such as schema flexibility, high availability and fault tolerance, and strong consistency over DynamoDB.

Step-by-step explanation:

Advantages of HBase over DynamoDB:

1. Schema flexibility: HBase allows for schema flexibility, which means you can easily change the structure of your database without any downtime. This is useful when dealing with evolving data models.
2. High availability and fault tolerance: HBase is designed to provide high availability and fault tolerance. It uses replication and distributed architecture to ensure that data remains accessible even in the event of hardware failures.
3. Strong consistency: HBase offers strong consistency, where each read operation is guaranteed to have the most up-to-date data. This is important for applications that require strict consistency requirements.
