All about Indexes
Indexes are essential to good database performance, but it can be hard to decide what indexes to create. In this session we'll look at guidelines for index creation
Indexes are essential to good database performance, but it can be hard to decide what indexes to create and the ‘rules’ around indexes often appear to be vague or downright contradictory.
In this full day session we’ll dive deep into indexes, have a look at their architecture and internal structure and how that affects the way that indexes are used in query execution. We’ll look at why clustered indexes are recommended on almost all tables and how their architecture affects the choice of columns. We’ll look at nonclustered indexes; their architecture and how query design affects what indexes should be created to support various queries.
