    What an outstandingly excellent explaination !!! Yes handling mutexes and semaphores has it's own throughput headaches

    Thank you Arpit, very nice way of explaining the whole concept behind the redis single threaded model.

    I used sorted redis sets in my company project for leaderBoard 😅, completely removing db here. Fetched the leaderboard combining two scores into one

    Redis is no longer open source now. Can we use redis community version for commercial websites now? What is the impact of changing the licensing policy for the Redis? Is it only for cloud support? What can I do with my existing redis integrated projects? How Valkey is substitution for Redis? Could you please make a detailed video on this?

      You can continue using it. It just prevents other companies from offering it as a managed service. No changes on your side.

    Network IO is slow but execution is fast (in memory ) implies it has no waiting data (queue of commands ) to process thus IO multiplexing seems to be a wonderful solution

    Hi Arpit , Is there a way we can limit number of tcp connection to redis at application layer in synchronous way ?

    • @sakshamjain16
      @sakshamjain16 2 роки тому +2

      Use Redis pool to limit connection

  • @liveforothers1846
    @liveforothers1846 Рік тому

    @arpit as you said redis create connection fromTCP and in a single thread all those connection comes and execute. But i have also seen i can only create one connection in redis and that one connection can also serve as many request as multiple connection does. Which is more scaleble single connection with multiple request or connection per request is the ideal practice

    @Asli Engineering :- I like the content of your playlist. Request you to make a series on Object storage technology ( a detailed one which covers the internal such as how the data is organised and stored on physical hardware ) .. I have been searching internet for this details but have not found anything so any kind of help would be highly appreciated.

    So the event loop thread is always busy, always checking if something is there to work on?

    Also what happens when you have data from multiple socket at a same time ,when you read? @18:00

    • @AshokBathini
      @AshokBathini Рік тому

      Not sure if redis uses epoll; I guess it may be using it.
      If u use epoll, u need to register fds(sockets) with it and whenever any related socket buffer is full, u get a handle on all those fds, process them sequentially and go back and ask for more fds whose buffer is full/ready to read.

    I have a query, how this eventloop works in multi core machines. Blocking calls issue is addressed because of event loop I agree but how we will achive parrallesim with multiplecore

    • @AsliEngineering
      @AsliEngineering  Рік тому +1

      It does not work on multi-core

    • @AshokBathini
      @AshokBathini Рік тому

      We have worked on something similar, built our own webserver using epoll systemcall. We just create a separate process per core.

    Hi Arpit, there will be concurrency issues if we have multiple shards/nodes of same redis instance? Since they both work separately even after being single threaded???

    • @Jollyrogger805
      @Jollyrogger805 3 місяці тому

      If you are referring to redis cluster, redis network io will still be single threaded thus no concurrency issue

    I am finding these videos so interesting! I'd love you ever make a video like these ones about how HFTS (High Frequency Trading Systems/Applications) work and especially all the optimisations required to achieve processing time in the order of microseconds or nanoseconds. Not sure if it is your area of expertise but I am sure you definitely have the knowledge for it.
    For example, I know that in many cases, they would avoid the use of threads to avoid waiting time in locks, data locality to take advantage of CPU L1 and L2 caches, lock free data structures, etc. Been reading a book about it recently, super interesting.
    HFTS is a super interesting topic, would love if you can produce some content :)
