HBTree: an Efficient Index Structure Based on Hybrid DRAM-NVM

Non-volatile Memory (NVM) with extremely high storage performance is the key storage device to build the next generation of storage systems. Various key-value (KV) store index structures have been designed for NVM, but these designs based on single level NVM suffer from significant write consistency overhead. The DRAM-NVM hybrid schemes improve the write performance but at the cost of very long re...
