Abstract

See full text

Techniques are described for identifying conflicts between a prospective temporal key and an index of temporal keys, the index sorted based on a time value associated with each of the temporal keys. Embodiments determine whether a first temporal key within the index of temporal keys conflicts with the prospective temporal key. Here, the keys within the index may be sorted based upon a respective time value associated with each of the keys. Upon determining that the first temporal key conflicts with the prospective temporal key, the prospective temporal key is designated as conflicting with at least one existing temporal key in the index of temporal keys.
