Abstract
Systems and methods are disclosed for processing queries against one or more dataset sources. The system tracks query resource data and resource utilization data. The query-resource usage data can indicate resources used to execute queries. The node resource utilization data can indicate current utilization of nodes in the system. Upon receipt of a query that identifies a set of data to be processed and a manner of processing the set of data, the system can use the query-resource usage data and the resource utilization data to define a query processing scheme. The query can then be executed using the query processing scheme. In some cases, the query coordinator can dynamically allocate partitions operating on worker nodes to execute the query.
