    Abstract: A credentials store definition identifying a remote credential store is received. The credential store definition includes access information to enable access to the remote credentials store. A credentials object is created in an internal database based on a credentials object definition. The credentials object identifies a security credential to retrieve from the remote credentials store to access an external resource. At runtime, a request to access the external resource is received, and based on receiving the request, the security credentials identified by the credentials object are retrieved from the remote credential store using the access information. The retrieved security credential is provided to a processing component to access the external resource.

    Abstract: Embodiments described herein provide techniques for in-line compiling of UDFs in other programming languages. These techniques enable faster programming iterations because it allows users to compile directly in the cloud processing system. Moreover, it allows the UDFs to tie into existing libraries. The compiled results are treated as sensitive and handled with appropriate security policies, as with any other user data in the system.

    Abstract: Disclosed are systems, methods, and non-transitory computer-readable media for a providing stored procedures in a network-based database system. A database system executes a stored procedure within a sandbox process. The sandbox process separates the stored procedure from the other services and processes of the database system and may also limit the resources (e.g., storage, memory, etc.) and functionality available to the stored procedure. Stored procedures are commonly designed to execute database queries that are processed by other components of the database system. To provide for secure communication between the stored procedure and the other components of the database system, the sandbox process is loaded with java database connectivity (JDBC) libraries (e.g., JDBC instance) that is modified to limit the communication abilities of the stored procedure.

    Abstract: A query referencing a function associated with a remote software component is received by a network-based data warehouse system. Temporary security credentials corresponding to a role at a cloud computing service platform are obtained. The role has permission to send calls to a web endpoint corresponding to the remote software component. A request comprising input data and electronically signed using the temporary security credentials is sent to a web Application Programming Interface (API) management system of the cloud computing service platform. The request, when received by the web API management system, causes the web API management system to invoke external functionality provided by the remote software component at the web endpoint with respect to the input data. A response comprising a result of invoking the external functionality is received from the web API management system, and the result data is processed according to the query.

    Abstract: External functions can provide users of a database system the ability to invoke external services while operating from inside the database system. The techniques described herein address may detect throttling by the external system and automatically adjust or modify a request rate accordingly. Also, the techniques described herein may increase the request rate to optimize the use of the resources provided by the external system. These techniques allow the database system to improve efficiency when working with external services, which may or may not be elastic or scalable. Moreover, these techniques can decrease query execution times and reduce costs.
