Work-in-Progress: An Improved Network Interface Card with Query Filter for Big Data Systems

In this paper we approach to accelerate the data processing of storage and computing separated big data systems. We propose an improved Network Interface Card with Query Filter (NIC-QF), implemented by FPGA on storage nodes, to accelerate the data queries, which can also reduce the workload and communication overhead on computing nodes. NIC-QF is designed with query filtering accelerator and Network Interface Card (NIC) communicator, which can filter the original data on storage nodes as an implicit coprocessor and directly send the filtered data to computing nodes of big data systems. Filter units in NIC-QF can perform multiple SQL tasks in parallel, and each filter unit is internally pipelined, which can further speed up the data processing. Experiments with two benchmarks demonstrate the efficiency of our approach, which can achieve average up to 65.56% faster than the traditional approach.
