Information processing method and apparatus, device, and storage medium

An electronic device, comprising:

• a processor and a memory in communication connection with the processor,
• wherein the memory stores computer-executable instructions, and
• the computer-executable instructions, when executed by the processor, cause the processor to implement an information processing method applied to a key-value storage system for key-value separation, wherein a storage unit in the key-value storage system comprises a key partition and a plurality of storage partitions, the key partition is used for storing log-structured merge tree (LSMT) information, the plurality of storage partitions are used for storing key-value information, and the method comprises:
• selecting, according to the LSMT information in the key partition, a target storage partition with a highest invalid information rate from the plurality of storage partitions comprised in the storage unit, wherein the invalid information rate is used for representing a proportion of invalid key-value information to total key-value information in the storage partition;
• detecting validity information corresponding to each key-value information in the target storage partition, and screening out valid key-value information from multiple key-value information stored in the target storage partition according to the validity information corresponding to each key-value information, wherein the validity information comprises being valid or being invalid;
• and
• transferring and storing the valid key-value information to a first storage partition except for the target storage partition, and erasing the multiple key-value information stored in the target storage partition.

A computer-readable storage medium, wherein computer-executable instructions are stored on the computer-readable storage medium, and the computer-executable instructions, when executed by a processor, cause the processor to implement an information processing method applied to a key-value storage system for key-value separation,

• wherein a storage unit in the key-value storage system comprises a key partition and a plurality of storage partitions, the key partition is used for storing log-structured merge tree (LSMT) information, the plurality of storage partitions are used for storing key-value information, and the method comprises:
• selecting, according to the LSMT information in the key partition, a target storage partition with a highest invalid information rate from the plurality of storage partitions comprised in the storage unit, wherein the invalid information rate is used for representing a proportion of invalid key-value information to total key-value information in the storage partition;
• detecting validity information corresponding to each key-value information in the target storage partition, and screening out valid key-value information from multiple key-value information stored in the target storage partition according to the validity information corresponding to each key-value information, wherein the validity information comprises being valid or being invalid;
• and
• transferring and storing the valid key-value information to a first storage partition except for the target storage partition, and erasing the multiple key-value information stored in the target storage partition.
