We present ColumnBurst, a memory-efficient, near-storage hardware accelerator for database join queries. While the paradigm of near-storage computation has demonstrated performance and efficiency benefits on many workloads by reducing data movement overhead, memory-bound operations such as relational joins on unsorted data have been relatively inefficient with fast modern storage devices, due to the limited capacity and performance of memory available on the near-storage processing engine. ColumnBurst delivers very high performance even on such complex queries, while staying within the memory performance and capacity budget of what is typically already available on off-the-shelf storage devices. ColumnBurst achieves this via a compact, hardware implementation of sorting-based group-by aggregation and join algorithms, instead of the conventional hash-based algorithms. We evaluate ColumnBurst using an FPGA-based prototype with 1 GB of slow on-device DDR3 DRAM, and show that on benchmarks including TPC-H queries with join queries on unsorted columns, it outperforms MonetDB on a 6-core i7 with 32 GB of DRAM by over 7x, and ColumnBurst using a near-storage hash join algorithm by 2x.
