Concurrency control scheme for key-value stores based on InfiniBand

Abstract

Using InfiniBand technologies, the performance of key-value stores can be greatly improved because of RDMA features and the ultra-low latency of InfiniBand. However, maximizing the benefits of InfiniBand for key-value stores is still challenging because of the data consistency problem between RDMAs and CPU-aware memory accesses. In this paper, we propose a concurrency control scheme to utilize the RDMA features of InfiniBand in key-value stores. The proposed scheme efficiently handles the race conditions among GET and PUT operations on the key-value store.
