    Thank you Kaivaly for the video, it was really well explained and the animations are amazing. I would like to point just one thing the title "Reinventing Kafka the right way" I think is not precise once the part that AutoMQ are improving is the Storage Engine system and not the Message Middleware Broker (if I understood correctly based on this video). It was more an opportunity to enhance an isolated component from Kafka for cloud storage instead a full rewrite. An example of "Reinventing the right way" in my point of view would be the ScyllaDB which has backwards compatibility with Cassandra although it was rewritten using C++. I wish the best brow keep going!!!! EDIT 1: And they created a platform over na existent Kafka concept

    Thanks for this interview. Great as always! One question: so if the WAL writes are batched and periodically flushed to storage, there in a window in which if the process crashes, the writes will be lost? I.e the client response that write is complete is not durable.

    • @TheGeekNarrator

      Thanks for watching. Yes, there are ways to configure the behaviour. This might help you slatedb.io/docs/faq/#what-happens-if-the-process-goes-down-before-slatedb-flushes-data-to-object-storage

    • @ShortGiant1
      @ShortGiant1 24 วันที่ผ่านมา

      Yeah that’s the “linger” stuff they spoke about. The client won’t get an ack about the write being successful until the flush happens. Therefore it would be as if the write request never happened (in practice the client would retry)

    This is super cool . Probably the only youtube video [> 1hr ] , which I watched in whole. I took a whole week to watch it ... made sure I understood every idea presented and discussed. Thank you so much. I have a question => The partition placement , is DDB still using consistent hashing , for deciding which partition goes to which node[physical server] ... or there is some other algorithm used now. The original Dynamo paper mentioned consistent hashing [I read half the paper] ... Precisely => 1. How is it decided which key goes to which partition ? 2. How is it decided which partition goes to which node[physical server] ? Consistent hashing ... works in a bit different way ... all of the people watching this video knows how . For example in normal consistent hashing I guess it is hard to keep a limit on partition size ... I have read some part of the original consistent hashing paper ... in my quest to understand that paper ... somehow I reached your video .. and I thank myself for that.

    why couldn't LiteFS just observe writes to .wal and propagate only those like you are doing at Turso? Also ... if I understood correctly the primary is location based so you'll have fast primary in Europe, as example, but writings from US will inevitably need to end up there first, right? I think this is also common for other DBs, but I just would like to be confirmed reads are always fast (once in each replica) but writes are also "primary location latency" based. Is this correct? Last, but not least, please don't talk trash on JS, it's pretty awesome after all :P
