Title: PERFORMANCE ANALYSIS OF' FILE ORGANIZATIONS THAT USE MULTI-BUCKET DATA LEAVES WITH PARTIAL EXPANSIONS
Authors: Gabriel Matsliach
PDFCS0643.pdf
Abstract: We present an exact performance analysis, under random insertions, of file organizations that use multi-bucket data leaves and perform partial expansions before splitting. We evaluate the expected disk space utilization of the file, and show how the expected search and insert costs can be estimated. The analytical results are confirmed by simulations. The analysis can be used to investigate both the dynamic and the asymptotic behaviors.

Keywords: search structures, performance analysis, multi-bucket data leaves, partial expansions.
