How to utilize Redis Streams

How to utilize Redis Streams

Redis, the in-memory multi-model database, is popular for many use cases. These include content caching, session stores, real-time analytics, message brokering, and data streaming. Last year I blogged about how to utilize Redis Pub/Sub, Lists, and Sorted Sets for real-time stream processing. Now, with the arrival of Redis 5.0, Redis has a new information structure developed to managing streams.With the Redis

Streams information structure, you can do a lot more than what was possible with Pub/Sub, Lists, and Sorted Sets. Amongst the many advantages, Redis Streams allows you to do the following:

  • Gather big volumes of information getting here in high speed (the only bottleneck is your network I/O);
  • Develop a data channel in between lots of producers and many customers;
  • Successfully manage your consumption of information even when producers and customers don’& rsquo; t run at the very same rate; Persist information when your customers are offline or detached;
  • Interact between manufacturers and consumers asynchronously;
  • Scale your number of consumers;
  • Implement transaction-like data security when consumers stop working in the middle of consuming information; and
  • Use your main memory efficiently.

The best part of Redis Streams is that it’& rsquo; s developed into Redis, so there are no additional steps needed to deploy or handle Redis Streams. In this post, I’& rsquo; ll walk you through the essentials of using Redis Streams. We’& rsquo; ll appearance at how we can add data to a stream, and how we can read that information (at one time, asynchronously, as it shows up, and so on) to please different consumer use cases.
