  • Publication number: 20250036302
    Abstract: A method and device for data access, electronic apparatus and storage medium are provided. The method for data access includes: writing a key of a first key-value pair to a host memory in response to a write request to write the first key-value pair to the memory database; determining whether to write a value of the first key-value pair to the host memory or a Computing Express Link (CXL) memory based on a length of the value of the first key-value pair; and writing the value of the first key-value pair to the host memory or the CXL memory, based on a result of the determination.

  • Publication number: 20230024734
    Abstract: A storage method includes determining layers that are to be merged in a database; determining a data block that is to be modified based on files of the layers that are to be merged in the database; reading a corresponding data block in the memory and reorganizing the read data block, according to a key corresponding to the data block that is to be modified; replacing the data block that is to be modified in the memory with the reorganized data block, when byte size of the reorganized data block does not exceed a first preset value; and storing the key and statistical information of the reorganized data block in a corresponding file of the database.

  • Patent number: 11537582
    Abstract: Provided is a data access method including generating an index corresponding to a key in a first key-value pair in response to receiving the first key-value pair, writing the key-index pair corresponding to the key and the index into a block storage device, the key-index pair being stored in the block storage device in a log-structured merge-tree (LSM-Tree) structure, writing an index-value pair corresponding to the index and the value in the first key-value pair into a key-value solid state drive (KV SSD).
