Data processing method, apparatus, and system

A data processing method, comprising:

• obtaining, by a second apparatus, an access frequency of a first data block, wherein the access frequency of the first data block is obtained based on an access frequency prediction model and a first feature of the first data block, the first feature comprises a read/write feature related to the first data block and a read feature of a second data block adjacent to the first data block, and the first data block is any data block in storage space;
• and
• determining, by the second apparatus, a type of each first data block in the storage space based on access frequency of each first data block.

A data processing apparatus, the operations further comprising:

• obtaining access frequency of a first data block, wherein the access frequency of the first data block is obtained based on an access frequency prediction model and a first feature of the first data block, the first feature comprises a read/write feature related to the first data block and a read feature of a second data block adjacent to the first data block, and the first data block is any data block in storage space;
• and
• determining a type of each first data block in the storage space based on access frequency of each first data block.
