Abstract: A method for managing resource consumption in a computing system where the resources are consumed by a plurality of user-defined functions (UDF) performing tasks for a database management system, wherein the UDFs are executed by a plurality of processes external to the database management system. The method comprises providing a resource policy by defining a plurality of threshold values relating to the resource consumption and performing an action e.g. queuing, rejection, suspension, as defined by the policy, on at least one of the UDF. The UDF may run fenced, meaning that they are not executed within the same process as the main database engine but rather by a separate external process i.e. its resource consumption is not controlled by the database management system. The resource policy may denote a rule or set of rules relating to one or more resources of a computing system together with a threshold value for the related resource and an action to invoke if threshold is exceeded.
