Abstract
A query placement system to receive a query from a client of a managed database service and identify a pool of processing clusters, respectively capable of processing the query. The query placement system randomly selects a first subset of two or more processing clusters from the pool of processing clusters. The query placement system sends the query to a first selected processing cluster in the first subset, wherein the first selected processing cluster is selected based on utilization data for the pool of processing clusters. The query placement system receives a response indicating that the selected processing cluster does not accept the query for execution, the response includes an estimated utilization for the query executing at the first selected processing cluster. The query placement system sends the query to a second selected processing cluster of the second subset based on the utilization data and the estimated utilization for the query.
