This application discloses a
database object processing method,
system, device, and medium, applied in the field of
database technology. In the mapping phase, the hierarchical identifiers (after removing hierarchical separators) of the original identifier key are concatenated into a hierarchical identifier string, generating a first
digital fingerprint. A mapping identifier key is generated based on the target start character, the target
digital fingerprint algorithm identifier, the first
digital fingerprint, the target hierarchical identifier length, and the hierarchical identifier string. In the inverse mapping phase, after determining that the mapping identifier key starts with the target start character, the hierarchical identifier string is segmented based on the target hierarchical identifier length to obtain each hierarchical identifier, generating a second digital
fingerprint. When the second digital
fingerprint matches the first digital
fingerprint, the hierarchical separator is used to restore each hierarchical identifier to the original identifier key. By constructing a unified bidirectional mapping mechanism, the
database cluster can be compatible with different
metadata services, significantly improving
system scalability.
