A system executes a set of database operations and determines counts of instances that each key is specified for a corresponding column by any database operations on a database table. The system identifies each key which is associated with any determined count that satisfies a threshold as a corresponding frequently accessed key. The system creates an optimized index for each column which stores any frequently accessed key. The system inserts each frequently accessed key into a corresponding optimized index. The system receives a database operation that specifies a specific key for a specific column in the database table. If any optimized index matches the specific column and stores any frequently accessed key that matches the specific key, then the system references a matching frequently accessed key in a matching optimized index to access a record, which is associated with the specific column and the specific key, via the database table.
