Methods, computer readable media, and apparatuses are provided herein for preserving custom metadata associated with an object (e.g., document) stored on a cloud data storage platform. An illustrative method may comprise receiving audit logs generated by the cloud data storage platform, and determining that the audit logs indicate a document exit event occurred from the cloud data storage platform. Further, the method may comprise storing in a cache memory, a document identifier associated with the document exit event, obtaining, based on the audit logs, custom metadata related to a document associated with the document exit event, and storing the custom metadata in association with the document identifier.
