Abstract

The present disclosure relates to an authority management method and apparatus, including obtaining authorization information from a received authorization SQL statement; adding a right record generated according to the authorization information to a column right data table of a metadata database when the authorization information includes a column identifier, and adding a right record generated according to the authorization information to a table right data table of the metadata database when the authorization information does not include a column identifier; when the access SQL statement isreceived, table-level authority verification being performed on the access SQL statement according to the authority record in the table authority data table, and column-level authority verification being performed on the access SQL statement according to the authority record in the column authority data table when the table-level authority verification is not passed. By performing permission verification according to the column-level permission data table and the table-level permission data table, the right management method and the device according to the disclosed embodiment can realize fine-grained right management in SparkSQL.

Description

technical field [0001] The present disclosure relates to the technical field of databases, in particular to a rights management method and device. Background technique [0002] Spark is a big data computing framework based on memory computing. It provides distributed computing functions, reads distributed stored data, and distributes tasks to each node for computing. Spark improves the real-time performance of data processing in a big data environment, while ensuring high fault tolerance and high scalability, allowing users to deploy Spark on a large number of cheap hardware to form a cluster. [0003] SparkSQL is a Spark-based distributed SQL (Structured Query Language) engine that supports SQL statements, which greatly facilitates users who are familiar with relational databases. [0004] Rights management refers to the security rules or security policies set according to the system. In the operation of the database, only authorized users can operate the database, and or...
