Introduction to Apache Kafka by James Ward

[@rohanurkude8503]

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 :)

[@geeeee8268]

Best Kafka intro by far.

[@zackmacomber]

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???

[@l_combo]

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

[@l_combo]

@@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

[@DevidasS]

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

[@scorpionkingnaveen]

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

[@sebkafka6330]

you're welcome

[@danuvian]

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

[@joakimhansson5687]

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

[@doviche]

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.

[@rodgersnyangweso6615]

Precise Intro. Kudos

[@dimuthul]

Thanks James Ward!

[@sreenivasaraju4988]

Nice presentation. Thanks

[@CarloL525]

Clearest explanation! Great talk!

[@fredramos2343]

Great video

[@mirmali2710]

I like James' way of presentation.

[@earlybird5612]

Great introduction to Kafka! Provides a great overview.

[@toenytv7946]

Great job.

[@jeffvoight6586]

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?

[@hotplugin]

Excellent intro with example

[@WayneTaylor1982]

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

[@goverdhank]

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

[@sheepyy15]

Awesome talk! thanks

[@srik006]

Excellent Presentation

[@CarlosEcheverriaOne]

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?

[@mehdimohammadi1623]

Awesome , it was very useful introduction I enjoyed that!

[@thanhtranvan8113]

How did you make the car moving?

[@JamesWard]

The code for that is at: github.com/jamesward/koober/blob/master/webapp/app/views/driver.scala.html#L88-L107

[@staticage]

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

[@channaly2772]

Awesome talk. Many thanks

[@benmathews533]

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

[@shellac23]

Great video!!!!

[@IMMLF]

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

[@JamesWard]

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

[@KAWADESUMIT]

Thank you for great information

[@theCanadian808]

Where can I find the slides for this presentation? Thanks

[@gustavkullberg9842]

Great talk!

[@muhammadtalha2363]

[@videojeroki]

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 ?

[@mvlad7402]

very nice

[@tormodkvalheim7214]

Thanks, great video! :)

[@sassynatan]

one of the best!

[@Luca1993x]

If you watch this on 1.25 times the speed, he and his movements look like a Sim-Character and its animations.

[@kosterix123]

could not resist.. indeed!

[@srinivasinf]

nice comment, its good with 1.25

[@jpwx]

When you want a good Kafka talk and the dude has the same damn name as you

[@mowzeyluts1111]

awesome ,thank you

[@BritainRitten]

Helpful talk!

[@SanthoshkumarNagulanchi]

Great tutorial....

[@robycohen]

Awesome..! Thank you..

[@SunnyG9]

This is great

[@bhanuprakash57]

Thanks 😊

[@iamabean]

Does anyone have the codes for this

[@JamesWard]

I think this is the sample I used: github.com/jamesward/hello-play-kafka

[@k.hemalatha4513]

Sound Introduction about Messaging system

[@xalfonso85]

thanks

[@darshanaweerasingha653]

Great :)

[@AmeeliaK]

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

[@kanaillaurent526]

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.

[@srinivas1363]

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

[@lhxperimental]

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.

[@dengan699]

save time, watch at 1.25!

[@1ma4ighter]

hey American people, is this guy Californian? asking cos of his accent

[@sebkafka6330]

I am a Kafka

[@ninovalentino]

why he seems so high

[@TheXV22]

is it me or is this guy really hard to listen to without losing attention?

[@CepGamer]

Интересная презентация, но боже мой, русские субтитры просто ужас. Query - корейцы?

[@kosterix123]

sorry, I fell asleep. Was it good?

[@javierleguizamon7889]

ZNQ

[@nguyen4so9]

This guy has never been in real world. Salesman only.

[@SanthoshkumarNagulanchi]

Salesman opens ide??.... see at 43:59... if you say him as salesman for this demo.... LOL you are not an IT guy..

[@superduck97]

Right.. and his reason for creating 370 repos on github was just to fool you. :)

[@MrLinuxFreak]

jamieward45?

[@cliffmathew]

Thanks
