The correct implementation of indexes is critical to improving SQL performance in any RDBMS. However, there are some basic problems regarding how MySQL and MySQL Storage Engines implement indexes in relation to other RDBMS products including Oracle.
In this presentation attendees will learn how to identify and verify MySQL index usage, what essential MySQL Tools exists for determining how to create better indexes and be able to verify the results of improvements. Understanding how the optimizer chooses indexes, generally only one index per table join and also the exceptions. Learn about advanced topics including covering indexes and partial column/prefix column indexes.
