provides engine authorization extensions to optimize the data security model to fine-grained row/column level. Please see the security page for more information. 1.3 High Availability Kyuubi is designed enabled by default, which only provides file-level coarse-grained au- thorization mode. When row/column-level fine-grained access control is required, we can enhance the data access model with the Kyuubi enables Kyuubi with data and metadata control access ability for Spark SQL Engines, including, • Column-level fine-grained authorization • Row-level fine-grained authorization, a.k.a. Row-level filtering
