Parallel Databases Revolutionize Data Processing, Unlocking Unprecedented Efficiency and Speed.
The article discusses the development and testing of three parallel join algorithms for relational database queries. These algorithms were created based on analytical models by Kearns, which help design parallel database systems. The models are divided into single step (one operation) and multiple step (multiple operations) categories. The algorithms tested include parallel nested-loop join, bucket (hash) join, and a pipelined version of the bucket join. Results show that all three models are accurate within about 8.5%, making them valuable for designing parallel database systems.
