Started in good intentions but soon fell into a confluent marketing guide. Also, I’m certain it wasn’t confluent who came up with the terms; serialization and deserialisation! 😂😂😂

[@andym1343]

I really appreciate the quality and intention of what Confluent are doing with these, but the videos are a little dated in that Confluent's interface has changed markedly enough that it gets a little tough to follow along

Hmmm. Having a Proxmox VE environment meant I could clone a ubuntu container, install docker-compose and have Bitnami/kakfa up and running faster than it too her to explain how to do it on their cloud.

Error: topic "music" does not exist or your api key does not have the ACLs required to describe it How to add ACLs to describe the topic?

[@sarathkumarbarathi9331]

This seems out of place in the playlist. The video talks about creating a topic even before the viewer is introduced to the concept of topic.

[@wenyushi8364]

Question: I'm a bit confused about the poem lines starting around the 4th minute of the video clip: why did you "assign" (correct me if this is not the most accurate word) the first poem line "All that is gold does not glitter" to 0 / partition 3 rather than 0 / partition 0? Since it's key is 1 - the first message. On my end, as I followed this order of producing/input "All that is gold" key 1 -> "Not all who wander" key 2 -> "Deep roots are not harmed" key3 -> "The old that is strong" key4, the partition allocation turns out to be Partition3, Partition 2, Partition1, Partition 5 correspondingly, where Partition0 and Partition 4 were left "in blank". Why so? Was the assignment totally arbitrary?

[@JordanCricketMoore]

An integer of 0 does not mean "go to partition 0". The bytes of the key are hashed using Murmur2 algorithm, then that result is modulo'd against the total number of partitions.

[@planetside11]

Does the CLI not work on Windows? I've already get the Windows Subsystem for Linux installed, but keep getting an error with the curl command you have here.

[@timkoch-gruenberg2899]

Love the Tolkien reference. And the video too.

Is it possible to make a cluster from workstations/ laptops with Kafka/Hadoop/Zookeeper run different OS's (like Windoze, Linux, OSX...) ?

[@adityanjsg99]

Yes... ! Make sure they are in same network.

[@Leo-ug5be]

I created the topic with the error 'Authorization failed'...

[@ayandamcanyana874]

hey did you resolve this problem

[@ericsphone6915]

I believe it's "All that glitters is not gold".

[@ConfluentDevXTeam]

That's the common quote, yes. However, in this case, Danica is correctly quoting from J.R.R. Tolkien. www.goodreads.com/quotes/229-all-that-is-gold-does-not-glitter-not-all-those

I realize that the confluent cloud is easy, but I really don't want to give them my credit card. I hope the talk about installation later...

[@MrDeeb00]

You can skip

[@smritigupta1468]

But now while creating the account they ask for card details, I am afraid to create one account, that later I didn't see, and they start charging somehow..

[@ConfluentDevXTeam]

Gilles here from Confluent. This is optional. You don't have to add your payment card and you can just press the 'Skip" button instead of clicking on the "Continue" button.

[@WillScrillz]

@@ConfluentDevXTeam You do have to enter your credit card, there is no Skip button.
