Methods and systems for identifying one or more indexes are described. A system can collect a set of database operations that were performed during a given time window. Next, the system can partition the set of database operations based on a set of database tables that were accessed by the set of database operations. Then, for each database table in the set of database tables, the system can determine a set of indexes that are candidates for improving database system performance. Next, based on the candidate indexes, the system can identify one or more indexes, one or more combinations of indexes, and/or a consolidated index that improve overall database system performance.
