How to use Redis with Python | for beginners | DevOps

Today we take a look at writing Python code to connect to a database. We extend our customer demo application to read and write data to a database.
We also take a look at high availability and scenarios to handle failures.

Apologies for any quality reduction, I edited this one on a plane with poor audio equipment. Had to push the limits to get this one out 💪🏽🙂

[@ole-jakobolsen3800]

Rarely do I comment on a KZbin video. But I got to here - don't understand how this fantastic content has only 10k views 🙌

[@keinezeit99]

Man what you do is amazing and we appreciate it. Thanks!

[@georgelza]

nice timing :)

[@Telepriester]

Great tutorial and super good explanations! Was very insightful and helped me a lot. Thank you very much for sharing this great content!

[@davidcote3915]

Amazing video! Perfect eleboration and very neat workflow! Next I'd ask 'how do we take snapshot in times?' If the cluster crashes, masters and slaves, what's the best way to prepare for disaster recovery? Writing to a nosql database? Dumping in a blob? How do you recover from a such backup? Thank you for the video!

[@stefanschmidbauer6075]

Nice, very helpful to see every step of the dev process in detail like that. Great job 💪 For Redis: I'd got for all reads go to slaves, all writes to masters, is that a general good practice?

[@MarcelDempers]

that's correct, that is a pattern many follows. it helps spread connections a little better. Thanks for the kind words 🙏🏼

[@robsonpedroso9679]

very good! tks

[@georgelza]

any chance you can share the environment (redis) parameters that you pass in, I must be missing where you create the connection and pass in things like the password (although your cluster from the previous video did not set a password in the configMap. - looks like masters are a comma del list of ip's for the master and the ip : port, ip:port an and sentinel you just pointing to one, would/could this be the k8S service sentinel or would this be a pod. why not point the master to the service ?

[@georgelza]

... my previous posting, when I tried to post via the sentinel, it complained about slots (I'm aware of what they are), wondering, have you tried multiple masters, with the slots (16k) split/defined for them, 3 masters each with say 2 replicates and the 3 sentinels.

[@fartzy]

Dang ur jacked bro. Nice video too

[@Aju-G]

Could you explain how Kafka work with microservices. How to deploy production lambda and it's code rollout. Working of APIgateway in aws

[@rauldeandrade]

Hi. I really love your videos. I've been looking for a while for content related to redis-stack and golang, but I haven't found anything comprehensive. I like the idea of how redis has different db types like redis graph and redis time series as well as their message queue. Could you do a follow up on your redis series to include a small micro service with redis, golang and their messaging queue and how it's different from using another messaging system like rabbitmq or kafka? I'm deeply grateful for all the knowledge you share with us and I've learned a lot from you that is practical implementation. Thank you

[@dharmaputra7394]

Request tutorial microservices with consul kubernetes

[@georgelza]

... I know you like running things straight in docker... but would/could be real nice if you maybe consider switching to k3d.. as it's closer to a probable deployment world. there are small nuisances that come into play with k8s thats not present in a straight docker drop. - friendly request.

[@rqd3]

we get it u lift

[@georgelza]

... next time George, watch more of video before asking questions, do have a question now though, where does "my master" come from ?
