Multi-streaming RocksDB

Abstract: This paper proposes a file-to-SSD stream mapping strategy for RocksDB-a widely used embedded NoSQL database. The proposed strategy steers data writes into separate SSD streams according to the lifetime of corresponding file data. Experiments show that the strategy improves the RocksDB performance significantly.
