performance - Mysql int vs varchar as primary key (InnoDB Storage Engine? - Database Administrators Stack Exchange
Saved by uncleflo on February 22nd, 2015.
I am build a web application (project management system) and I have been wondering about this when it come to performance. I have an Issues table an inside it there are 12 foreign keys linking to various other tables. of those, 8 of them I would need to join to get the title field from the other tables in order for the record to make any sense in a web application but then means doing 8 joins which seems really excessive especially since I am only pulling in 1 field for each of those joins.
