The differences and usage scenarios between Redis and Redisson frameworks

Redis and Redisson are two important tools in modern in-memory data storage and distributed data storage. Redis is an open source in-memory database that supports different data structures such as strings, lists, hash tables, sets, etc. Redisson is a distributed data service framework written in Java language, which can easily map Java objects to distributed storage.

Redis and Redisson have some same usage scenarios, such as:

1. Caching: Both Redis and Redisson can be used as caches because they can both store data in memory and read it quickly Pick.
2. Distributed lock: Both Redis and Redisson support distributed locks, which can ensure data synchronization in a multi-node environment.

However, Redis and Redisson are implemented differently, making them more suitable for use in certain scenarios. The following is a detailed introduction to their differences and usage scenarios.

1. Redis

Redis is a memory-based data storage technology. It supports different data structures including strings, lists, hash tables, sets, etc. The following are the main features of Redis:

1. High performance: Redis is an in-memory database that can read and write data very quickly.
2. Persistence: Redis supports persisting data to disk so that data can be restored after restarting the server.
3. Distributed: Redis can be used as a distributed database, implemented through multi-node replication and sharding.

Usage scenarios:

1. Cache: Redis can be used as a cache because it can quickly read and write data, which can improve the performance of the program to a certain extent.
2. Session storage: Redis can store session data because it can read and write data quickly.
3. Counter: Redis can be used as a counter because it supports increment and decrement operations.

2. Redisson

Redisson is a distributed data service framework written in Java language. It supports different data structures such as objects, collections, maps, etc. The following are the main features of Redisson:

1. Easy to use: Redisson provides a simple and easy-to-use API to easily map Java objects into distributed storage.
2. High availability: Redisson uses multi-node replication and sharding to achieve high availability, ensuring automatic switching to standby nodes in the event of node failure.
3. Extreme performance: Redisson uses asynchronous IO and Netty network framework to optimize performance, providing the best performance and throughput.

Usage scenarios:

1. Distributed collection: Redisson's distributed collection allows programs to access the same data collection on multiple nodes at the same time, such as user lists and products. List etc.
2. Distributed lock: Redisson distributed lock is a reentrant lock that can synchronously access shared resources in a distributed system on multiple nodes, such as databases, files, network resources, etc.
3. Distributed objects: Redisson's distributed objects allow programs to store Java objects in distributed storage, so that the same Java object can be used on multiple nodes at the same time, improving the scalability and scalability of the system. performance.

Conclusion:

Redis and Redisson are both very useful tools that can be used in different scenarios. For some simple needs, Redis is sufficient. However, when a project needs to deal with complex distributed data structures, Redisson is the first choice. At the same time, Redis and Redisson can also be used in combination to complement and optimize the implementation.
