In-memory Representations of Databases via Succinct Data Structures: Tutorial Abstract

Abstract

In recent years, the field of succinct data structures (SDS) has grown rapidly. SDS store data in main memory space that approaches an information-theoretic minimum, and support operations on the data with little or no slow-down compared to their conventional counterparts. In practice, an SDS uses one to two orders of magnitude less main memory than a conventional data structure. For this reason, SDS are becoming a popular approach for storing data that is only somewhat bigger than main memory. This tutorial explores the fundamentals of SDS and their applications to a variety of database problems.
