Distributed Systems in One Lesson by Tim Berglund
Вставка
- Опубліковано 29 лип 2024
- Normally simple tasks like running a program or storing and retrieving data become much more complicated when we start to do them on collections of computers, rather than single machines. Distributed systems has become a key architectural concern, and affects everything a program would normally do-giving us enormous power, but at the cost of increased complexity as well.
Using a series of examples all set in a coffee shop, we’ll explore topics like distributed storage, computation, timing, messaging, and consensus. You'll leave with a good grasp of each of these problems, and a solid understanding of the ecosystem of open-source tools in the space. - Наука та технологія
Tim's lectures are so funny and captivating that I can binge on them instead of Netflix.
I don't know if it is a natural skill from this speaker, but he speaks in a very clear way that i can watch the talk in 1.5 speed. Thank you.
Tim has a knack for explaining things in a clear and intuitive way. A great teacher, I hope he does more of this. Regards from Chennai.
Many thanks!
"I am the very definition of mutable state" Awesome. I think I may need to steal this. Thank you Tim!
Amazing single place to know about Distributed system, tools and techniques.
Thanks for sharing...
Gavin Belson? :O
Lol
:xD Haha...
I got confused after seeing this comment :p
Dude same here ! I also thought on what earth Gavin Belson is here...
Yeah. You kind of nailed it. ;-)
WTF lol hooli
What a great speaker
very concise and to the point !
This is Jeff Winger fron Community tv show LOL
Same thoughts.

wonderful presenter, great delivery of crisp information.
Thanks for the lessons m Berglund. This was by far one of the educating 40 minutes I had in years. I'd like to thank you for sharing your knowledge.
Glad it was helpful!
made it pretty clear from start to end. thank you for sharing.
A great speaker , at the same time an expert and pro educator :) I love your speech, wish I could have your presentation skills..
Love this video ❤️ didn't expect such an amazing content to be available for free. Internet is really a bliss most of the times
Glad you enjoyed it!
Well the idea is that you later go buy Confluent’s services 😉 Kafka is a monster to maintain yourself
"I like americano today, tomorrow maybe [...] mocca with extra foam - I'm the definition of mutable state" 😂
Mllk
Simply love the way Tim Bergland covers the topics. Excellent skills displayed.
Many thanks!
This talk brings some light into all these technologies and helps decide what to learn next.
He had worked in cassandra in earlier and now for kafka. Dude, you are the evolution of the distributed systems.
Great introduction to Distributed Systems. So often the industry gets bogged down in buzzwords and cliche terms that newcomers find it difficult to know where to begin. This is a great starting point.
Marketing loves to obfuscate.
I love this guy. Cristal clear and definitely he loves distributed systems.
A great piece of presentation from a great speaker.
Great speaker n teacher! Thanks for sharing!
Amazingly explained. Interesting speaker :)
Great content on introduction to Distributed Computing. I enjoyed the session. Thank you Tim.
Glad it was helpful!
Awesome talk, great learning on distributed systems
Excellent speaker, that was pure joy
Can you share the link to the 4-hour lecture about distributed systems you mentioned in the start, please?
one hell of insight full talk on distributed system
Really enjoyed listening to this lecture, thanks :)
Nice talk. It feels like watching a good movie :)
Great job Tim, nice stuff.!!
I was inspired by this and another talk about system design (parking lot with premier parking spaces). I n your honor I am adding an external drive, for the hidden- read/write copy of a groupware system with an asynchronous don't ask don't tell, storage management unit. The best i ever had... The best i ever had ......
Thanx sir very helpful..
Presentation was great and explanation was clear. Thank you!
Glad you enjoyed it!
the original lesson is on Oreilly and its amazing
Great presentation
Great introduction to Distributed Storage, Computation, & Messaging.
Glad you liked it
It was a very good lecture. Thanks for the talk
great video, awesome explanation
Thanks , its a great session !!!
As a full stack developer who does stand up on the side, gotta say that was one tough crowd :D
Sad
he has good explanations
He is also Hooli's CEO.
This is correct
Thats a great insight on distributed systems. One thing at 42:00 Tim mentioned about consistent hashing, where as in example of topic partitioning he used modules operation, which doesn't derive consistent hashing.
Can someone point me to the link for the 4 hr video, he referenced to?
Also interested.
Can we have the link to the 3-4 hr long video Tim talked about?
Anyone else noticed: "Kakfa" in the heading of the slide :O..
ya thats awsome
Amazing
Such a powerful video
Awesome speaker. Wish I could deliver talks in this manner.
Love him as well
Excellent speaker holy moly.
great presentation, thank you!
Glad it was helpful!
Tim is amazing
Best explanation of Cassandra and consistent Hashing in all of UA-cam
Thank you
very inspiring!
Great lecture!
Thank you!
Great presentation👏
Very good presentation
great content!
4:29 I thought my laptop was being possessed by Satan for a second.
Is "read replication" synonymous with multiversion concurrency control? Meaning, you have different versions of data items for each transaction that are distinguished by time stamp, and therefore avoiding conflicts?
No, it means a given version has X identical redundant copies.
and they're usually kept on separate servers, racks, or data centers.
Really appreciated very nice
very well explained core concepts and problems about distributed systems, thanks Tim
Glad you enjoyed it!
Nice talk.
Super cool presentation. I am also not a fan of football, but I like Cervantes, so my favorite football club is Real Madrid.
"zed's dead" - the audience didn't get this. Hope so I did :)
awesome talk.
45:37 "They say the best code is the code you never write and the worst code would be the code you write two or more times" 👏
Akshay AS except good code is usually rewritten until it’s great, so this isn’t quite true.
Very nice explanation
Thanks for liking
Instant like for over simplified CAP theorem at 20:00
6:41 "In a relational database, reads are usually than writes" I don't understand this. I thought reads are generally more expensive since you might have joins? While when writing you typically add some rows to a single table and that's it.
Can somebody help explain it to me?
Or I guess it's because in a distributed system you have to synchronize the writes to other machines?
I think he meant more reads than writes in terms of volume.
Because OLTP databases do a great job of caching and using indexes to optimise read. Even the storage characteristics and disk layout is usually optimised for read traffic.
He meant there are usually more reads than writes, this is why the first step is to have some replicas to use for the reads
Its really a good talk...
23:00 about cap theorem.. did he confuse himself?
He almost made it seem like by not having availability, you would also lose consistency, but what he means is, if the node just doesn't respond, it's still consistent because it's not giving out bad/inconsistent data. In a big distributed system, this data could be retrieved from elsewhere while tolerating the consistency.
nice talk thank you!
10:03 picks up bottle. 10:08 opens it to drink water (presumably) 10:24 shuts and keeps it back without drinking
Haha that's swag
23:28
i didn't know about all these pain involved with distributed system.
great talk
Question on Topic Partitioning (at 41:00): together with each message, can we not include the timestamp when it was produced? Wouldn't it provide the global ordering?
Tim's a beauty.
Thanks
Misspelled Kafka ("kakfa") on the slide at 34:10.
Love this video as I prepare for sys design interview
Glad it helped you.
Nice talk..
Very clear
You can skip to 2:47 if you want.
Dude... F*** you...
What if I tell you that you read 'kakfa' as 'kafka' 33:07
33:03 kafka is not spelled correctly at the top there
One of few people where you can run the video at 2x speed and still understand what he is saying.
That's not a good thing
apache sparkling water?
All this Hadoop/Spark thingy are so abstract that I have no clue what is what anymore. 🤣😂
The focus of this video is Distributed Systems when writes and reads getting slower on Databases. What about application server getting too many requests? Why is that not covered as part of a problem that DS solves?
Because you scale the application server horizontally and load balance across the servers/processes
33:05 kakfa
Why still water over sparkling water?
Good entry-level talk, but also would be great to give credits to Leslie Lamport, touch upon CRDTs (Conflict-Free Replication Data Types), mention consensus solutions like RAFT and Paxos, explain SQL vs NoSQL vs NewSQL, say PACELC (extended CAP), add an overview of consistency models (what is strong serializability?), and talk about leader election.
I know, too much, but that's the essence of distributed computing!
shameless plug at 5:46
17:00 that order though
that z thing is funny, especially in Poland :)
:)
"I draw examples from a coffee shop just to be cute". Ha ha.. Of course there is a dire need to be cute in this otherwise one hell of a hard core tech talk.
This is Jeff Winger fron Community tv show LOL
Gavin Belson ! :p
Anyone noticed that Tim looks like Benji Dunn?
If you are in front of the mic, always go with the still water :P
It is one of the Top10 Speakers' pro tips 😂
@@DevoxxPoland It should be the most important tip :P
Continue watching: 12:42
I am here for the second time!
Awesome
This is good, but of course, very briefly.
