Method enable_url_table

datafusion/core/src/execution/context/mod.rs:414–432

Enable querying local files as tables. This feature is security sensitive and should only be enabled for systems that wish to permit direct access to the file system from SQL. When enabled, this feature permits direct access to arbitrary files via SQL like ```sql SELECT * from 'my_file.parquet' ``` See [DynamicFileCatalog] for more details ``` # use datafusion::prelude::*; # use datafusion::{

(self)

    /// # }
    /// ```
