    Excellent information. Though I had to increase the play speed to 1.5 to maintain my sanity.

      try at 0.25 speed, it will become ASMR

      I go 1.5 normally on all of his videos, but then that became the "normal speed", so I went to 1.75 and was still able to follow him with no problem.
      His content is great, but I need that speed boost to for it to maintain my attention 😂

    I have a doubt though; the B Tree Index you explained in the video, isn't that B+ Tree in actual ?

    This is the second time I come back to this video. Still amazes me how great the whole playlist is. I don't understand, however, why there must be only one clustered index per table.... can't we just update the leaf nodes whenever we update the table?

    • @coreblaster6809
      @coreblaster6809 9 часов назад

      "Simply put: a clustered index IS the table. It organizes the data itself in a certain way.
      Thus, you can have only one clustered index per table."

    Maximum search time in ordered table should be rounded up, isn't it? For instance: There're 5 steps needed to find Al Rabeeah.
    But the most thing - your course is awesome & helped me a lot, thanks!

    Good and well structured information. But the speech is very slow. Listening at speed of 1.25 or 1.5 worked well.

    My instructor provided links to your videos for us to listen to. They chose poorly. You talk SO SLOWLY. I can read ten times faster (at least) than you talk. It. Drives. Me. CRAZY!!!
