We hardly see someone explaining such a vast topic in such a concise and clear way. Really appreciate all the effort James, Kudos to you :)

Best Kafka intro by far.

I wish Apache's documentation read like he speaks...I have been so confused about the AdminClient API and various Kafka Java libraries and this guy actually defines terms in a clear way...why can't the vendors themselves present their products clearly???

Kafka is open source... so it's up to the community to define.

@@kjeldschouten-lebbing6260 if you are writing and submitting code, I would expect you to at least comment your code at the very least and then documentation on top. The open source community has produced plenty of documentation in their time but obviously may not have the same incentive as a funded company i.e. Confluent

Wow.. That was a absolutely great intro to Kafka. Thanks for that!

Good intro to Kafka. Easy to understand and it was explained well. Very good speaker.

Really an awesome presentation this one! cant help but keep coming back to this video to go back to the basics of Kafka..

Clearest explanation! Great talk!

Great stuff. Would recommend repeating questions from the audience though as we can't hear it at all.

Thanks for the talk here. Very informative and great working life example

Great introduction to Kafka! Provides a great overview.

Very good introduction. I've bought the book Kafka The Definitive Guide and it's all just so amazing. Guys, drop traditional messaging system brokers and adopt the Kafka way.

Awesome talk! thanks

Precise Intro. Kudos

nice comment, its good with 1.25

Writes straight to disk might be a problem for anyone using virtual servers with attached storage.Latency would be a killer, not to mention the overhead of having multiple nodes, even with pagecache to socket enabled. Other factors also come into play e.g. log compacting etc

thanks

If a message gets a guaranteed commit to a leader, is it eventually guaranteed to make it to the quorum? If not, what happens to it?

Thanks

Sound Introduction about Messaging system

Great :)

very nice

Excellent talk. By any chance, are thee slides shared somewhere ? Thanks

Can we use consumer-groups on top of two Kafka Clusters, which are replicated using MirrorMaker? If yes, will Kafka warranty the "Exactly One Time Delivery" policy?

i have frequently thousand of files to process. each files takes about 5min. Can kafka distribute thing king of process over computers on my lical network ?

Where can I find the slides for this presentation? Thanks

save time, watch at 1.25!

Maybe a bit off-topic question, but how the presentation was made? Is there a tool for creating such presentations?

I used Reveal.JS: github.com/hakimel/reveal.js/

When talking about a new technology, it is best to stick to super conventional stuff around it - like the langauge and libraries. Don't mix Kafaka with Akka and a currently in fashion JVM language.

How did you make the car moving?

I'm confused. These comments seem to contradict each other: @40:34 - A source is something that produces events, and the sink is something that consumes the event. @44:58 - I create a plainSink which is... my sink is going to be the way that I get messages into Kafka. @45:34 - code comments: // sink is incoming driver messages // source is outgoing rider messages

@JamesWard

A sink in Akka Streams can receive messages which then get sent to Kafka. This gets tricky because in this example everything is bidirectional. There is a Kafka Sink and a Kafka Source. But also a websocket Sink and Source. Connected together like: Browser -> WebSocket Source -> Kafka Sink -> Kafka -> Kafka Source -> WebSocket Sink -> Browser

Here's the code example he used: github.com/jamesward/koober

Does anyone have the codes for this

Great but the use of the word "node" everywhere confuses me. It seams like one partition is a node, one consumer also is a node if I got it correctly. For him, node is a general term for defining a unity element.

Hi kanail, here node is nothing but a Kafka broker server which actually maintains the copy of partitions.
