US Patent 10162597 Identifying IO access pattern in unique database structures

Certain database structures and operations are recognized in order to generate hints for a tiered storage array. Historical snapshots of a database data dictionary are searched for patterns corresponding to the structures and operations. After a structure or operation is identified, a corresponding set of extents is identified. Logic predicts future activity associated with the extents, and a corresponding hint is provided to the storage array. Statistical information associated with the identified structure or operation may be maintained and updated to facilitate prediction of activity.
