What are the uses of Couchbase databases?

The purposes of using Couchbase database include the following aspects:

1. Cache: Couchbase can be used as a caching layer for applications, storing hot data in memory to provide fast read and write performance.
2. Distributed caching: Couchbase allows data to be distributed across multiple nodes and utilizes consistent hashing algorithm to route and manage data. This makes Couchbase a scalable and highly available distributed caching solution.
3. Data storage: Couchbase can serve as the primary solution for storing and managing both structured and unstructured data for applications. It supports various data storage models, such as key-value pairs, documents, graphs, and full-text search.
4. Real-time Analytics: Couchbase has the ability to support real-time analytics applications, enabling complex data analysis and query operations through its built-in data indexing and query engine.
5. Session storage: Couchbase can be used as a solution for storing sessions, managing and storing user session data. It offers high availability and high-performance session storage, as well as support for complex session queries and analysis.
6. Data synchronization: Couchbase can be used for data synchronization and replication, allowing data to be copied from one Couchbase cluster to another in order to achieve data backup, disaster recovery, and distributed data deployment.

In general, Couchbase is a versatile database solution that can be applied to various scenarios and applications.
