Cost of MySQL Indexes?
I'm curious what impact Indexes have on the performance of MySQL and ultimately my website...
For example, what is the "cost" of a Standard Index in MySQL?
And what is the "cost" of a Unique Index in MySQL?
And how about the "cost" of a Primary Key/Index?
For example, I have a table with the following Fields and associated Indexes...
- id (PK) - slug (Unique Index) - name (Unique Index) - created_on - updated_on
I feel guilty having 3 Indexes of a Table with only 5 Fields, but what are you going to do?!
