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! 😂😂😂
Seamless like a Knife through butter!
WATCH apache kafka 101: topics video before this one, they swapped them in the playlist it seems like
very nice presentation style.
new fan/subscriber here
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.
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.
Love the Tolkien reference. And the video too.
All those wander are not lost ??
confluent login --save command on WSL command line brings up the browser but gets stuck. I would appreciate any help on this matter.
Hello, I have followed the doc for installing confluent through wsl but it's consumer is disconnecting and giving errors I tried all approach but nothing worked, can you guys connect and help me out.
Confluent is up and running
Producer is connecting but consumer is not connecting
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?
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.
Is it possible to make a cluster from workstations/ laptops with Kafka/Hadoop/Zookeeper run different OS's (like Windoze, Linux, OSX...) ?
Yes... ! Make sure they are in same network.
Hi!
Can you help me please?
When I run the following command: "confluent api-key create --resource lkc-pr2o1y" i get the following error:
Error: Confluent Cloud backend error: error getting service account: Bad Request. Must contain id or email
The way to login is through SSO

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.
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?
damn good. what should be done in case your ingress exceeds 100MB/s?
Error: failed to obtain topics from client: API key may not be provisioned yet

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..
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.
getting error "Error: failed to obtain topics from client: API key may not be provisioned yet"
Got the above error because I am using VPN. After disconnecting it, it worked.
@@MudduKrishnaMallipeddi i ma not using any vpn but still got the same error whats the problem
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...
You can skip
