Data processing method and apparatus

A data storage method, comprising:

• obtaining to-be-written data and a first key corresponding to the to-be-written data;
• searching a learned index model for a first leaf node corresponding to the first key;
• determining, according to a first model algorithm corresponding to the first leaf node, a first storage unit corresponding to the first key, wherein the first storage unit corresponds to one or more pieces of user data, wherein when the first storage unit corresponds to a plurality of pieces of the user data, the first storage unit stores a first pointer pointing to a collision array, or when the first storage unit corresponds to one piece of the user data, the first storage unit stores the user data;
• and
• storing the to-be-written data into the collision array to which the first pointer points, or storing the to-be-written data into the first storage unit.

A data processing apparatus, comprising a memory and a processor, wherein the memory is configured to store computer instructions, and the processor is configured to invoke the computer instructions from the memory and run the computer instructions, to;

• obtain a first key corresponding to to-be-read data;
• search a learned index model for a first leaf node corresponding to the first key;
• determine, according to a first model algorithm corresponding to the first leaf node, a first storage unit corresponding to the first key, wherein the first storage unit corresponds to one or more pieces of user data, wherein when the first storage unit corresponds to a plurality of pieces of the user data, the first storage unit stores a first pointer pointing to a collision array, or when the first storage unit corresponds to one piece of the user data, the first storage unit stores the user data;
• and
• search the collision array to which the first pointer points for the to-be-read data, or determining the user data stored in the first storage unit as the to-be-read data.
