RedisStream is an abstract data type represented in memory, what it does is implement more powerful operations to overcome log file limits.

That makes?

makes redis streams the most complex type, despite the fact that the data structure is quite simple.

This does a set of operations that blocks and in turn allows consumers to wait for products to add new data to a flow.

Maybe it is not an update opinion but it is an idea of ​​what we can do using Stream and in turn it can clear up certain doubts in the forum.

I was reading the documentation a few days ago, RedisStream allows you to create applications similar to Kafka.

with this you can:

  1. Create applications that publish and consume messages. although this is new to us since you could also do it with Redis Pub / Sub.
  2. Consume messages that are published even when the client application is not running, here if there is a big difference with Redis Pub / Sub.
  3. Consume messages starting from a specific point.

Apart from this RedisStream also has the same concept of consumer groups. RedisStream Consumer Groups allow client applications to consume messages in a distributed manner, making it easy to expand and build highly available systems.
