Systems and methods are disclosed for processing queries against an external data source utilizing dynamically allocated partitions operating on one or more worker nodes. The external data source can include data that has not been processed by the system. To query the external data source, a query coordinator can generate a subquery for the external data source based on determined functionality of the data source. The subquery can identify data in the external data source for processing and a manner for processing the data. In addition, the query coordinator can dynamically allocate partitions operating on worker nodes to retrieve and intake results of the subquery. In some cases, number of partitions allocated can be based on a number of partitions supported by the external data source.
