A complete implementation of the symmetric hash join algorithm using modern C++20 coroutines. This implementation demonstrates distributed-style joining of two datasets using hash partitioning, ...

Abstract: Text-Based Information Retrieval (IR) is a field where the search in a large document is a basic concept. Concise queries are very fundamentals process in order to satisfy user’s need for ...

First we pre-process the data. It is required to partition the triples into relations by using vertically partitioned approach, namely for each distinct property, set up a table with ’Subject’ and ...

We analyze the costs, and describe the implementation, of three hash-based join algorithms for a general purpose shared-memory multiprocessor. The three algorithms considered are the hashed loops, ...
