Data storage method, apparatus and storage medium

A data storage apparatus, comprising a processor, a storage device, and a computer program, wherein the computer program is stored in the storage device and is configured to be executed by the processor, the computer program comprising instructions for executing the method comprising:

• receiving a data storage request from a client, wherein the data storage request comprises data to be stored;
• determining a state of the data to be stored to be a hot data state when a least frequently used (LFU) of the data to be stored is greater than a first preset threshold, a least recently used (LRU) of the data to be stored is greater than a second preset threshold, and length information of the data to be stored is smaller than a third preset threshold;
• otherwise, determining the state of the data to be stored to be a cold data state;
• determining a corresponding storage medium for the data to be stored according to the state of the data to be stored;
• and
• storing the data to be stored in the corresponding storage medium determined for the data to be stored;
• wherein the data to be stored comprises a key and a value, and the computer program comprises instructions for executing the method comprising:
• sorting the data to be stored according to the value of the data to be stored, and storing the sorted data to be stored in the storage medium.
