Redis

What is?

Redis is an OpenSource non-relational database whose structure includes key-value storage. Redis has strategies for storing data in memory and on disc, guaranteeing fast response and data persistence. The main use cases for Redis include caching, session management, PUB/SUB.

• Allows reprocessing
• Consumer Groups
• Minimal latency
• No need for zookeper
• Takes up far fewer resources than Kafka/RabbitMQ

Negative Points
