Did you know?

WebbIt employs a multi-column LSM-tree data layout based on key ranges. Compaction tasks on multiple NDP devices are performed in parallel, improving compaction performance. MStore increases the width of the LSM-tree level to reduce the depth, which reduces the execution time and write amplification of compaction. WebbThe experimental results show that the pipelined compaction procedure can increase the compaction bandwidth and storage system throughput by 77% and 62% respectively. …
