Just-in-Time Index Compilation
Creating or modifying a primary index is a time-consuming process, as the
index typically needs to be rebuilt from scratch. In this paper, we explore a
more graceful "just-in-time" approach to index reorganization, where small
changes are dynamically applied in the background. To enable this type of
reorganization, we formalize a composable organizational grammar, expressive
enough to capture instances of not only existing index structures, but
arbitrary hybrids as well. We introduce an algebra of rewrite rules for such
structures, and a framework for defining and optimizing policies for
just-in-time rewriting. Our experimental analysis shows that the resulting
index structure is flexible enough to adapt to a variety of performance goals,
while also remaining competitive with existing structures like the C++ standard
template library map.Comment: Work Supported by NSF Award #IIS-161758
