  • Patent number: 11928029
    Abstract: A system that implements a data storage service may store data for a database table in multiple replicated partitions on respective storage nodes. In response to a request to back up a table, the service may back up individual partitions of the table to a remote storage system independently and (in some cases) in parallel, and may update (or create) and store metadata about the table and its partitions on storage nodes of the data storage service and/or in the remote storage system. Backing up each partition may include exporting it from the database in which the table is stored, packaging and compressing the exported partition for upload, and uploading the exported, packaged, and compressed partition to the remote storage system. The remote storage system may be a key-value durable storage system in which each backed-up partition is accessible using its partition identifier as the key.

  • Patent number: 11855801
    Abstract: A system receives vehicle metric data from a gateway device connected to a vehicle. The vehicle gateway device gathers data related to operation of the vehicle and/or location data. The system receives data from multiple vehicles in a fleet. The vehicle gateway device gathers vehicle metric data at a high frequency. Instead of transmitting a large amount of vehicle metric data at a fine level of granularity, the vehicle gateway device aggregates and buckets the vehicle metric data over a period of time (such as, every five minutes). The system uses the bucketed data for fleet management analysis.

  • Publication number: 20230336547
    Abstract: Methods, systems, apparatuses, and computer-readable storage mediums are described for authorizing publishing of a message and/or a subscription from an Internet of Things (IoT) device. In an example system, a message broker receives a list of attributes from a claims provider. The message broker determines whether publishing of the message is authorized based at least on the list of attributes, and publishes the message if it is determined that the publishing is authorized. The message broker may also receive a subscription specifying a topic filter. The message broker determines whether the subscription is authorized for the IoT device based at least on the list of attributes, and transmits a subscription message to the IoT device if it is determined that the subscription is authorized.

  • Patent number: 11327949
    Abstract: A system that implements a data storage service may store data for database tables in multiple replicated partitions on respective storage nodes. In response to a request to back up a table, the service may export individual partitions of the table from the database and package them to be independently uploaded (e.g., in parallel) to a remote storage system (e.g., a key-value durable storage system). Prior to uploading the exported and packaged partitions to the remote storage system, the service may verify that the exported and packaged partitions can be subsequently restored, which may include unpackaging and/or re-inflating the exported and packaged partitions to create additional unpackaged copies of the partitions, re-importing the additional unpackaged copies of the partitions into the database (e.g., as additional replicas), and/or comparing checksums generated for the exported partitions with checksums generated for the additional unpackaged copies of the partitions.

  • Patent number: 11283892
    Abstract: A technology is described for managing dynamic groups of devices using device representations. An example method may include receiving a request for a dynamic group of device representations. In response to the request, a membership parameter used to identify member device representations included in the dynamic group of device representations may be obtained. Device representations may be queried using the membership parameter to identify member device representations that have a state that corresponds to the membership parameter, and the dynamic group of device representations may be generated to include identifiers for the member device representations.

  • Patent number: 11271896
    Abstract: A technology is described for operating a device shadowing service that calculates an aggregated group state for a group of device representations. An example method may include receiving device states for devices represented using a group of device representations, where the devices connect over a network to a device shadowing service configured to manage the device states. In response to an event, device representations included in the group of device representations may be identified. Device states indicated by the device representations may be obtained and an aggregated group state for the group of device representations may be calculated using the device states indicated by the device representations.

  • Patent number: 11036591
    Abstract: A system that implements a data storage service may store data for database tables in multiple replicated partitions on respective storage nodes. In response to a request to restore a given table that was backed up in a remote storage system (e.g., key-value durable storage system), the service may create a new table, and may import a copy of each of the partitions of the given table from the remote storage system into the new table. The request to restore the table may specify a modified value for a configuration parameter for the table or for one of its partitions. The service may apply the new configuration parameter value to the table or its partitions during the restore operation. The new configuration parameter value may indicate an increase or decrease in storage capacity or throughput capacity, and its application may automatically trigger a partition split or move operation.
