Abstract: A device to be utilized for testing a program is connected to a device host operating in a service provider network via a peripheral bus. A network connection is established between a testing host, which might be a virtual machine, and the device host using a peripheral-bus-over-network-protocol. A secure network connection is established between the developer computing device and the testing host. A network port utilized by a debugging client application executing on the developer computing device is forwarded to the testing host over the secure network connection. Data packets generated by the debugging client application executing on the developer computing device are forwarded to a debugging server application execution on the testing host. Peripheral devices (e.g. the requested device) accessible to the testing host can then be utilized by the developer computing device for testing execution of the program as if the device were locally connected thereto.

Abstract: Materialized views may be generated at a managed materialized view platform that accepts data streams as a source. When updating a materialized view with a data stream as a source, a stored portion of the stream is used to maintain a history of changes to be made. When a join operation needs to utilize the data stream source to determine an update to the materialized view, the data stream is preserved to complete the join and update the materialized view.

Abstract: The maintenance of a materialized view created and managed by a materialized view management platform may be dynamically adjusted. The performance of updates to a materialized view are monitored to trigger different events to make adjustments to the performance of subsequent updates. The materialized view management platform can adequately scale to handle changes to data sources as inputs to the maintenance of the materialized view, as well as make other adjustments handle various changes in the capability of the target data store to receive updates to the materialized view (e.g., target data store outages).

Abstract: A technology is provided for a fan out for a subscription. A mutation may be received at a data proxy from an application. The mutation may be sent to the data source via a data access resolver associated with the data proxy. Results for the mutation may be received. At least one subscription may be identified which matches combinations of fields in the results for the mutation. A message for the at least one subscription regarding the mutation may be sent to a messaging service to enable the messaging service to publish the message to devices subscribed to at least one topic for the at least one subscription.

Abstract: A technology is provided for conflict resolution in a data proxy for a mutation. A mutation may be received at a data proxy from an application, and the data proxy is in a service provider environment. The mutation may be sent to be processed by a data store via a data access resolver. A conflict message may be received at the data proxy via the data access resolver for a conflict mutation at the data store for the mutation. The conflict may be resolved at the data proxy using a conflict resolution function in the data proxy.

Abstract: A technology is provided for mutations with immediate feedback. A mutation may be received at a data proxy from an application. The mutation may be sent to a data source via a data access resolver associated with the data proxy. Results of the mutation may be received from the data source. A subscription may be triggered based on receiving the results of the mutation. A message may be sent via a topic provided by the subscription by using a messaging service such that the messaging service publishes the message with the mutation to devices subscribed to the topic.
