@ahmetb
I was reading your book and got tired at the beginning of chapter 8 then I found your YouTube channel while trying to watch some videos before I dig into the chapter! Thanks for all your work in making this field more understandable.

As soon as I find enough time I'm going to go through all the series. Thank you for making the effort.
@krizh289
Thanks for putting these lectures on youtube--education should be accessible to all
@IrvinHerreraGarza
Mr. Kleppmann , I love your book and the way you explain things in your videos. Thank you so much for creating this material.

Delighted to watch the series. Thanks for creating this. I am already grateful to you because of "DDIA"
@nakonachev1407
Great lecture, straight to the point. Thanks for the effort put into it and the adequate way of explaining it.
@mikedelta658
Crystal clear explanation. Hats off to you, Martin!

Great lectures, Great book, Great author 👍
@ashishkalra9438
Please correct me if i missed something..Before client sends commit message to coordinator for 2 phase commit start..it perform normal transaction on replicas but my confusion is if the problem happens during that write i.e. one replica performed write but another fails then how two phase will help...i thought that the entire reason of two-phase commit is to perform write in prepare phase and the commit in commit phase...why we are allowing normal update to both replicas before 2pc can start the process.

Wow, I didn't know Martin has a YT channel. Instant subscribe.
@leon_thinks
Grateful for the amazing lecture! Finally, get some impression about how Raft works.
@lifeirao7605
super illustrative. Thank you!
@OffAndGo
Hello, the video is so helpful but hope that my question can be clarified, best. Does the coordinator node care if other nodes have committed successfully or not, if it does and a node failed to commit, does the coordinator make a second decision for sending an abort to all the nodes?
@za406
Question: Why is the "prepare" message necessary if replicas "ack" on the original transaction message?
@abcdef-fo1tf
Am I right in understanding that we can use raft to send total order broadcasts and elect new coordinators for node communication and two phase commit for commiting data?
@danish6192
Why client is opening transaction simultaneously on 2 nodes in 2PC ? shouldn't the transaction be open on master node only ?
