This application provides a data access method, a data lake, and related devices for use in a data lake. For a data lake comprising a client, a metadata management node, and an object storage system, the client can request the metadata management node to locate the object path of a data block in a file and generate and encrypt corresponding access tokens at the data block level. Access control for each data block can be achieved through these access tokens. After the client sends an object access request, including the object path of the data block and the encrypted access token, to the object storage system, the object storage system performs strict security authentication on the object access request using the information in the decrypted access token before performing read / write operations based on the object path of the data block. This significantly reduces the risk of data leakage, effectively prevents unauthorized access, enhances data security, and ensures secure data access between the object storage system and the metadata management node in the data lake.
