@WebDevCaptain So how do you merge 2 4GB chunks? Won't they result in an 8GB chunk overflowing the memory?

Sort a 1TB file when you only have 8GB RAM. You literally cannot load it all in memory. How do you do it efficiently?

MySQL performance starts with one rule: measure first. Guessing leads to random indexes and broken queries.

@0xAhm3d It’s all about usecases, we don’t fall in love with technologies we use them.

@KhaledMosaad_ agree, let’s just ditch Larry Ellison and run MariaDB. and InnoDB is GPL-licensed, so we should be safe from Oracle, I think.

MySQL innoDB is the best trust me bro
Ahm3d@big_data_eng

مفيش افضل في المطلق، ممكن اقول Postgres هو الاقوي بس تيجي مع binary data حيبقى فاشل وساعتها mongoDB حيكون هو الخيار الافضل. الداتا دايما هي اللي بتفرض عليك ايه نوع ال database اللي حيتم استخدمها معاها، وهنا بيظهر مين الشاطر الفاهم اللي يقدر تختار ال tool المناسبة، من. الحمار الي حافظ ومش فاهم 🧠

@big_data_eng That’s fair, I’m just saying that most real-world data still fits a relational model pretty well, so SQL ends up being the go-to a lot of the time. And yeah, I just prefer MySQL over PostgreSQL

@FahadCoding You also have to give credit to Denis Ritchie and Ken Thompson for the foundations of Linux, since it is essentially a reimplementation of Unix.

@DevanshuXi It is mainly used to minimize the number of I/O operations per query. AVL trees have two children, whereas B-trees can have many more. As a result, you can usually reach the target page with fewer I/O operations.
