Abstract: Systems and methods are disclosed for a streaming service generating an aggregation of data streams in response to a query from a client device for data streams matching the query. The aggregation of data streams matching the query is presented to the requesting client as a single virtual stream. The streaming service modifies the virtual stream in real-time by adding data streams matching the query that come online to the virtual stream, or deleting data streams from the virtual stream that go offline. The streaming service can partition the virtual stream if the data flow rate increases above a threshold, and reduce partitions if the data flow rate falls below a threshold. The client device can add or terminate consumer processes in response to changes in the data flow rate and partitioning.

Abstract: The described technology is generally directed towards a hybrid copying garbage collector in a data storage system that processes low capacity real chunks and virtual chunks (which reference data on other storage systems) into real chunks with a relatively high data capacity utilization. Real and virtual chunks with low capacity utilization are detected and copied into a higher capacity utilization real chunk, after which the low capacity chunks are deleted and their space reclaimed. As a result, much of the virtual chunk data that is to be migrated into a real chunk in the data storage system is migrated during garbage collection instead of as a separate migration process. Only the virtual chunk data that is relatively high capacity needs to be processed into real chunks by a separate migration process.

Abstract: Example embodiments of the present invention provide a method, an apparatus, and a computer program product for authenticating a request from a first domain to access a resource in a second domain according to credentials in the first domain. The method includes receiving, from the first domain, an assertion in the second domain and generating, according to the assertion, a token configured to be redeemed by a client in the first domain to access the resource in the second domain. The token then may be provided to the first domain.
