Abstract: A system that implements a data storage service may store data in multiple replicated partitions on respective computing nodes on behalf of clients. A storage node may, based on the amount of provisioned resources on a given storage device or logical volume, identify candidate partition management operations to be performed, and may send information about the operations to a central partition management scheduler. The scheduler may apply a global prioritization scheme to determine an order in which to perform the candidate operations. The order may be based on whether the operations include partition splits or partition moves, whether they aim to reduce provisioned storage capacity or reduce throughput capacity on a storage device or logical volume, whether they conflict with each other, whether the total number of partitions (or replicas thereof) involved in partition management at any given time exceeds a pre-determined limit, or whether they were requested by clients.

Abstract: Data streams are received for processing by a query. The query is associated with expected input data stream types and expected output data stream types. The received data streams are evaluated to determine if they correspond to the expected data stream types. If the received data stream types define data for a physical quantity that is defined in a unit of measure that is not the expected unit of measure, then unit conversion is required. Predefined mappings are utilized for performing required unit conversions and an optimal solution for conversion is determined. The unit conversions are performed automatically by unit conversion operators that are integrated within the process of generating of a runnable query. The runnable query is deployed and executed to generate result output streams that match the expected output stream type.
