Using char(36) as a uuid

Hello,

I was thinking about the use of integer as primary key of the table or use a char(36) as UUID in the entire project,
What I dont like about the integer, is the auto increment number, So I decided to use char(36) 'cause cake automatically fill it with an UUID, but I dont know if this can slow down the search in DB.

So, anyone who used this before, please tell me about that.

Is that right to use this in tables like: Users, Cars, Categories?


Thanks.
