Redis is awesome...

Cache
In-memory DB with persistence
Message broker

Plain awesome.

Hi @Redis Team!
Suppose A redis stream with "stream_key1" is published in one services "A" and there is another service "B" which is the consumer, but service B have three instances, and same message will be consumed by all three instance, how to avoid the processing duplicacy in this scenario, If i go with using consumer Id then it will leads to creating 'n' consumer Ids and we can't track on it.

simply superb... how to use redis as message broker

is XTRIM free up memory?
on XDEL when all messages are marked deleted then will it free memory?

Hi,
Is it better to use XTrim ou XDel for removing "processed" streams?

Hi Redis team!

Can you cover some more examples in real life which data structure to use for which situation like if 2 data structures accomodate 2 scenarios

This seems very useful, but i am a little confused doesn't blpush/blpop achieve same thing to some extent, blpop keeps blocking until new data arrives, but this seems to have buffer too like kafka*

[mayikx]

I don't understand, is Redis trying to replace Kafka?

[cryptolicious]

sweet, cant wait to try this tomorrow

Streams is an important topic, but that beard is a distraction 😂😂😂

I wonder what is the best way to mix stream with pubsub. my use case: consume published expired event into stream? or what would be the best way to use ttl of entreis to triger job with the expired entrey value/key
