Systems and methods are disclosed for processing queries against multiple dataset sources. One dataset source can include indexers that index and store data. The system can receive a query that identifies a set of data to be processed and a manner of processing the set of data. The set of data can include a first dataset that is accessible by one or more indexers and a second dataset that is accessible by one or more other dataset sources. A query coordinator can define a query processing scheme for obtaining and processing the set of data that includes a dynamic allocation of multiple layers of partitions. The partitions can operate on multiple worker nodes. The query can then be executed based on the query processing scheme.
