Do not use the uuid value as a primary key, the performance is horrible. use a normal auto increment primary key instead. however you are totally fine to store the uuid in a non primary key field. – progman jan 2, 2018 at 20:04 @progman, a couple of things about that horrible performance. it appears that the uuid is being stored raw in a char (36). This is your primary key, you don't want it to be slow. at its bit level, a uuid is 128 bits, which means it will fit into 16 bytes, note this is not very human readable, but it will keep storage low, and is only 4 times larger than a 32 bit int, or 2 times larger than a 64 bit int. This code is for benchmarking the performance impacts of using different types of id for the primary key in a database, but can be easily modified to benchmark other aspects. steps run composer install to install the necessary packages. set up a mysql database somewhere and make it remotely accessible.

Use a string type, not an integer. better is only better if it solves a problem. if you're really concerned about lookup speed, use a synthetic (auto increment) primary key. you can place a unique constraint on the uuid column, and use it only once to look up the synthetic key which is subsequently used for your joins etc. paulprogrammer 14721. I already have systems that use mysql, and i would prefer to stay with the same dbms. i prefer uuid v4 because of its physical machine independence. alternatives. i could simply create a trigger that calls the uuid function, as outlined in mysql alter table to automatically put in a uuid, but the uuid function generates uuid v1 ids.
