Abstract
Techniques for accessing data objects using UDF streams include decoding by at least one hardware processor of a first computing node, a first request for a UDF. The first request is generated at a second computing node by one of a plurality of input streams of the UDF. A second request for one or more data objects associated with the UDF is generated at the first computing node using an execution thread assigned to the first request. An authorization of the execution thread is performed using data access rights assigned to the first request. The one or more data objects are retrieved based on the authorization in response to the second request. The one or more data objects are stored in a storage location accessible by the execution thread.
