Directory metadata operation method and apparatus, electronic device, and readable storage medium

A directory metadata operation apparatus, comprising:

• at least one processor;
• and
• a memory connected to the at least one processor in a communication way;
• wherein the memory stores instructions executable by the at least one processor, to:
• in response to receiving a directory query request, obtain a query path carried in the directory query request;
• obtain a prebuilt prefix directory data table and a prebuilt full load directory data table, wherein a key of the prefix directory data table is a prefix path of directory metadata, the prefix path is a subpath corresponding to a hierarchy other than a default hierarchy counting from end in a path corresponding to the directory metadata, a value of the prefix directory data table is the directory metadata, a key of the full load directory data table is identification information of the directory metadata, and a value of the full load directory data table is the directory metadata;
• determine a matching result between the query path and the key of the prefix directory data table;
• determine a query result based on the matching result and the full load directory data table;
• wherein to determine the matching result between the query path and the key of the prefix directory data table, the at least one processor is further caused to:
• determine whether the prefix path in the key of the prefix directory data table contains a target prefix path, wherein the target prefix path is a subpath corresponding to a hierarchy other than a default hierarchy counting from end in the query path;
• in response to the prefix path containing the target prefix path, determine the matching result to be a successful matching;
• in response to the prefix path not containing the target prefix path, determine the matching result to be an unsuccessful matching;
• wherein in response to the matching result being the successful matching, the at least one processor is further caused to determine prefix directory metadata corresponding to the target prefix path;
• and
• successively query each hierarchy of the directory metadata below the prefix directory metadata in the query path from the full load directory data table, and determine the query result.

A non-transitory computer-readable storage medium, storing computer instructions which are executable by at least one processor to:

• in response to receiving a directory query request, obtain a query path carried in the directory query request;
• obtain a prebuilt prefix directory data table and a prebuilt full load directory data table, wherein a key of the prefix directory data table is a prefix path of directory metadata, the prefix path is a subpath corresponding to a hierarchy other than a default hierarchy counting from end in a path corresponding to the directory metadata, a value of the prefix directory data table is the directory metadata, a key of the full load directory data table is identification information of the directory metadata, and a value of the full load directory data table is the directory metadata;
• determine a matching result between the query path and the key of the prefix directory data table;
• determine a query result based on the matching result and the full load directory data table;
• wherein to determine the matching result between the query path and the key of the prefix directory data table, the computer instructions are executable by at least one processor to:
• determine whether the prefix path in the key of the prefix directory data table contains a target prefix path, wherein the target prefix path is a subpath corresponding to a hierarchy other than a default hierarchy counting from end in the query path;
• in response to the prefix path containing the target prefix path, determine the matching result to be a successful matching;
• in response to the prefix path not containing the target prefix path, determine the matching result to be an unsuccessful matching;
• wherein in response to the matching result being the successful matching, the computer instructions are executable by the at least one processor to determine prefix directory metadata corresponding to the target prefix path;
• and
• successively query each hierarchy of the directory metadata below the prefix directory metadata in the query path from the full load directory data table, and determine the query result.
