| Outline of Final Research Achievements |
In this research, we researched high performance data processing using advanced devices. Among them is the improvement of distributed database performance. Read Atomic Multi-Partition (RAMP) transactions are high-performance processing methods for managing foreign key constraints, secondary indexes, and materialized views in a distributed database management system. Although RAMP transactions have been enhanced by mitigating isolation, techniques to improve them by advanced devices are unexplored. Therefore, in this research, we proposed a method to accelerate RAMP transaction using InfiniBand, which is a high performance interconnect, using the function of Remote Direct Memory Access (RDMA). The result won the Information Processing Society of Japan Yamashita Memorial Research Award.
