摘要
A method and an apparatus that optimize operations for a key among a collection of key indexed data structures using meta data describing properties of the key with respect to the collection of data structures are described. The meta data may correspond to a cache dynamically updated to indicate invariants which are true for the key in a current state of the collection of data structures. Expensive calculations to search through the collection of data structures for the key may be avoided. For example costly lookup operations over a collection of data structures may not be required at all if a key is known to always (or to never) reference certain specific values or for these values to have certain meta properties in any of the collection of data structure globally throughout a system at a current state.
