# Hazelcast

> Use this tool when you need to manage and interact with distributed data structures, such as key-value stores, queues, and sets, in a scalable and secure manner. Hazelcast solves problems related to data distribution, caching, and real-time data processing, providing features like cluster discovery, access controls, and SQL queries. It accepts various inputs, including JSON and Compact serialization formats, and outputs data through multiple transport options, making it suitable for use cases like live streaming feeds and real-time data analysis.
