Abstract

Embodiments of the present invention relate to run-length encoded sequences and supporting efficient offset-based updates of values while allowing fast lookups. In an embodiment of the present invention, an indexing scheme is disclosed, herein called count indexes, that supports O(log n) offset-based updates and lookups on a run-length sequence with n runs. In an embodiment, count indexes of the present invention support O(log n) updates on bitmapped sequences of size n. Embodiments of the present invention can be generalize to be applied to block-oriented storage systems.
