Abstract
Iceberg queries are a special case of SQLqueries involving GROUPBY and HAVING clauses, wherein the answer set is small relative to the database size. We present here a performance framework and a detailed evaluation within this framework of the efficiency of various iceberg query processing techniques. Based on these results, we provide a simple recipe algorithm that can be implemented in a query optimizer to make appropriate algorithmic choices for processing iceberg queries.
