Abstract: Disclosed herein are embodiments of systems and methods for synchronizing file-catalog table with a file stage. In an embodiment, a data platform receives a notification of a modification to one or more files in a file stage. The file stage includes data storage having a storage location. The data platform updates, based on receiving the notification of the modification, a first file-catalog table for the file stage based on the modification. The first file-catalog table includes a row for each file in the file stage, as well as a column for each of one or more metadata properties of the one or more files in the file stage.

Abstract: A file access system for user defined functions (UDFs) can be implemented on a distributed database system. The system can store UDF signatures and interfaces (e.g., classes, sub-classes) that can be called by other users. Upon a UDF being called, one or more interface objects (e.g., InputStream) can be created and requests transferred to a execution node via a network channel. The execution node can implement multiple threads that are authorized and download file data from a staging location (e.g., internal stage, external stage) concurrently.

Abstract: A method includes decoding, by at least one hardware processor, a request for a user-defined function (UDF). The request includes a reference to one or more files. The method further includes generating, by the at least one hardware processor, the UDF based on the request. The UDF includes a file reference object with file path information corresponding to the reference. The file path information identifies a file path to the one or more files. A UDF call into the UDF is detected. The UDF call specifies the file path information. The UDF call is processed to generate result data using the one or more files.

Abstract: A file access system for user defined functions (UDFs) can be implemented on a distributed database system. The system can store UDF interfaces and file reference objects that can be called by other users. Upon a UDF being called, files on a stage, one or more interface objects (e.g., InputStream), and file reference objects can be implemented by execution nodes of the distributed database system. The execution nodes can implement multiple threads that are authenticated and can download file data from a staging location concurrently.

Abstract: Disclosed herein are systems and methods for population of a file-catalog table for a file stage in a user account on a data platform. In an embodiment, a data platform receives, from a client associated with a user account, a request to populate a file-catalog table of the user account based on a plurality of files stored in a file stage of the user account. The data platform responsively executes a list-files table function with respect to the file stage to generate a database-table object having a row for each file stored in the file stage. The data platform populates the file-catalog table of the user account based on the database-table object generated by the list-files table function.

Abstract: Disclosed herein are systems and methods for implementing a file-catalog table for a file stage. In an embodiment, a data platform receives, from a client, a request that the data platform create a file-catalog table for a file stage of a user account associated with the client, where the file stage contains one or more files at a storage location. The user account includes a file-stage object that corresponds to the file stage and that includes an indication of the storage location. In response to receiving the request, the data platform creates the file-catalog table for the file stage. The file-catalog table lists the one or more files in the file stage, and includes at least two different metadata properties of the files listed in the file-catalog table.

Abstract: A data platform provides support for unstructured files, semi-structured files, and structured files. In various different embodiments, the data platform provides functions for obtaining relative paths, absolute paths, and presigned URLs for files in internal and external stages; application programming interfaces (APIs) for integrating with external functions; built-in file-catalog tables; integration with cloud-storage platforms; customized views for flexible file-sharing options, stage-encryption options; notification integrations; table functions for generating file-catalog tables; streams on stages; streams on tables; and other features.
