Accelerating Hash Based Query Processing Operations on FPGAs by a Hash Table Caching Technique
Extracting valuable information from the rapidly growing field of Big Data faces serious performance constraints, especially in the software based database management systems (DBMS) In a query processing system, hash based computational primitives such as the hash join and the group by are the most time consuming operations, as they frequently need to access the hash table on the high latency off chip memories and also to traverse whole the table. Subsequently, the hash collision is an inherent issue related to the hash tables, which can adversely degrade the overall performance.
