Method, apparatus, device and storage medium for managing index

An apparatus for managing an index, comprising:

• at least one processor;
• and
• a memory storing instructions, the instructions, when executed by the at least one processor, cause the at least one processor to perform operations, the operations comprising:
• determining a target index for target data stored in a database, the target index including a corresponding index tag for identifying a stored version of the target index, wherein the target index indicates a storage location of the target data in the database;
• acquiring, based on the target index, the target data stored in the database, the target data including a corresponding data tag for identifying a stored version of the target data, wherein the index tag and the data tag are stored in different positions of the database;
• determining that the index tag of the target index does not match the data tag of the target data;
• and
• determining, in response to the index tag not matching the data tag, an operation associated with the target index by:
• generating a set of indexes associated with the target data;
• determining whether the set of indexes includes the target index;
• and
• modifying, in response to the set of indexes including the target index, the index tag based on the data tag such that the index tag matches the data tag.

A non-transitory computer readable storage medium, storing a computer program thereon, wherein the computer program, when executed by a processor, causes the processor to perform operations, the operations comprising:

• determining a target index for target data stored in a database, the target index including a corresponding index tag for identifying a stored version of the target index, wherein the target index indicates a storage location of the target data in the database;
• acquiring, based on the target index, the target data stored in the database, the target data including a corresponding data tag for identifying a stored version of the target data, wherein the index tag and the data tag are stored in different positions of the database;
• determining that the index tag of the target index does not match the data tag of the target data;
• and
• determining, in response to the index tag not matching the data tag, an operation associated with the target index by:
• generating a set of indexes associated with the target data;
• determining whether the set of indexes includes the target index;
• and
• modifying, in response to the set of indexes including the target index, the index tag based on the data tag such that the index tag matches the data tag.
