Faster Joins , Self - Joins and

We propose a new algorithm, called Stripe-join, for performing a join given a join index. Stripe-join is inspired by an algorithm called \Jive-join" developed by Li and Ross. Stripe-join makes a single sequential pass through each input relation, in addition to one pass through the join index and two passes through a set of temporary les that contain tuple identiiers but no input tuples. Stripe...

The summit.

of the programs (interventions) are on the horizon. Although such evaluations are not intended to be threatening , there is a pervasive fear that any findings that are critical will bear negatively on the ability to attract funds for future activities. But, the potential threat that could be associated with negatively perceived findings raises caution flags relative to participating in evaluati...

Inspector Joins

The key idea behind Inspector Joins is that during the I/O partitioning phase of a hash-based join, we have the opportunity to look at the actual data itself and then use this knowledge in two ways: (1) to create specialized indexes, specific to the given query on the given data, for optimizing the CPU cache performance of the subsequent join phase of the algorithm, and (2) to decide which join...
