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...
متن کاملThe Joins Concurrency Library
Cω extended C 1.x with a simple, declarative and powerful model of concurrency join patterns applicable both to multithreaded applications and to the orchestration of asynchronous, event-based distributed applications. With Generics available in C 2.0, we can now provide join patterns as a library rather than a language feature. The Joins library extends its clients with an embedded, type-safe ...

متن کاملInspector 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...
متن کاملSearch Joins with the Web
The lecture discusses the concept of Search Joins. A Search Join is a join operation which extends a local table with additional attributes based on the large corpus of structured data that is published on the Web in various formats. A Search Join takes as input a local table, a corpus of heterogeneous Web tables, and a description of the attributes that should be added to the local table. The ...
