Abstract
A log-structured merge-tree (LSM-Tree) based key-value (KV) data storage method includes writing KV data into a NAND flash memory. The KV data includes a key-value pair including a key and a corresponding value. The KV data is stored in a key-value solid state drive (KVSSD), which includes a storage class memory (SCM) and the NAND flash memory. The method further includes storing metadata of the KV data in the SCM. The metadata of the KV data includes the key and index information of the corresponding value of the KV data, and the index information of the corresponding value of the KV data indicates address information of the KV data in the NAND flash memory.
