Should We Create Indexes for All Foreign Keys?
The creation of indexes on foreign keys can up the speed of database queries. On the contrary, it’s not a good decision to utilize a large number of indexes. By the way, only index creation of columns that are frequently used in a query is recommended. The ideal columns to index are the ones used in JOIN operations, in WHERE clause, and in ORDER BY clause. Indexes on these fields will significantly increase your query speed.
