In parallel querying architecture, query optimization, partitioning, and synchronization play key roles. The optimizer divides the query into smaller tasks, partitioning assigns tasks to available processors or servers, and synchronization ensures successful completion of the tasks without conflict.
In this paper, we propose a comprehensive and practical solution for parallelizing query optimization in the multi-core processor architecture, including a ...
