The disclosed embodiments provide a system for processing data. During operation, the system obtains a user-defined function (UDF) that is defined using a standard UDF interface for accessing multiple platforms. Next, the system converts data in a platform into a standard form that is supported by the standard UDF interface using a platform-specific wrapper for the UDF and a platform-specific implementation of the standard UDF interface. The system then generates output data in the standard form by applying one or more operations to the data in the standard form. Finally, the system converts the output data into a platform-specific form that is supported by the platform and returns the output data in the platform-specific form.

Platform-independent user-defined functions for data access

Method, system, and programs for balancing work load in a distributed system. A plurality of multi-dimensional load metrics are received from a plurality of resource units in the distributed system. Based on the received plurality of multi-dimensional load metrics and a global statistical load model, a load deviance for each resource unit is computed. The plurality of resource units in the distributed system are then ranked based on the load deviance of each resource unit. At least one load balancing action is further determined based on the ranked resource units and at least one load balancing policy.
