1. A data processing method, comprising:
receiving a logical address corresponding to data to be processed;
storing the logical address into a first storage pool as a first access unit;
determining a mapping relationship between a physical address of the data to be processed and the logical address, after storing the logical address to the first access unit;
based on the mapping relationship and a data capacity of the first access unit, generating a first mapping table corresponding to the first access unit;
combining, according to a data capacity of a second access unit, a plurality of logical addresses of a plurality of first access units into a logic address group and storing the logic address group into a second storage pool as the second access unit so as to process the data based on the second access unit in a case that a quantity of the stored first access units in the first storage pool meets a requirement;
generating, based on the data capacity of the second access unit, a second mapping table corresponding to the second access unit.
