Patent number: 11675501Abstract: At a data stream management service, a first set of metadata indicating that a first isolated read channel has been associated with a first data stream is stored. The first isolated read channel has an associated read performance limit setting. A second set of metadata indicating that a second isolated read channel, with its own performance limit setting, has been associated with a data stream is also stored. Based on determining that the difference between a metric of read operations associated with the first channel and the read performance limit setting of the first channel meets a first criterion, the service initiates a throttling operation for reads associated with the first channel. The throttling decision is made independently of read metrics of the second channel.Type: GrantFiled: September 4, 2020Date of Patent: June 13, 2023Assignee: Amazon Technologies, Inc.Inventors: Vasudeva Gade, Benjamin Warren Mercier, Sayantan Chakravorty, Yasemin Avcular, Charlie Paucard

Patent number: 11070645Abstract: A data delivery service of a service provider may receive respective job specifications for different data transfer jobs between computing infrastructure collections (e.g., data centers). A job specification for a data transfer job may include an amount of data to be transferred for the data transfer job, one or more destinations of data transfers for the data transfer job, and/or one or more flexibility parameters for successful transfer of the data for the data transfer job (e.g., a deadline to transfer the data, available data delivery techniques). The data delivery service may determine a schedule for performing different data transfer jobs between two or more infrastructures based on an analysis of the amount of data to be transferred for each job, the destinations of the data transfer for each job, the flexibility parameters for each job (e.g., included in the respective job specifications), and the connectivity between computing infrastructure collections.Type: GrantFiled: December 14, 2018Date of Patent: July 20, 2021Assignee: Amazon Technologies, Inc.Inventors: Benjamin Warren Mercier, Thomas Bradley Scholl, Douglas Brian Terry, Craig Wesley Howard

Patent number: 10805238Abstract: A journal service maintains a journal that holds a number of journal entries. Access to the journal entries is controlled by providing a lead resource with access to a named role associated with the journal. A pool of alternate resources containing potential replacements for the lead resource is maintained. A succession order may be established for the pool of alternate resources, and individual resources in the pool of alternate resources may be managed based at least in part on their position within the succession order. The succession order may be established using various criteria that are indicative of a likelihood that a particular alternate resource will be available if the lead resource fails, such as the presence of shared points of failure between the current lead resource and an alternate resource. The lead resource may be replaced with an alternate resource as a result of various impeachment events.Type: GrantFiled: September 23, 2016Date of Patent: October 13, 2020Assignee: Amazon Technologies, Inc.Inventors: Christopher Richard Jacques de Kadt, Benjamin Warren Mercier, Carlos Vara Callau, Timothy Daniel Cole, Aaron Gifford Freshwater, Sayantan Chakravorty, Allan Henry Vermeulen

Patent number: 10666569Abstract: A journal service manages a journal that holds a number of journal entries. Journal entries are provided to the journal service by one or more producer services, and the journal service provides journal entries to one or more consumer services. Lead consumers retrieve journal entries from the journal service by specifying a named cursor which identifies a location within the journal from which the journal entries are retrieved. The journal service may select a lead producer and a lead consumer from a collection of candidate producers and consumers using a fitness score determined for each candidate producer and consumer. The fitness score may be based at least in part on the processing capability, predicted reliability, and cost of each candidate producer and consumer. The journal service may replace a lead consumer or producer with an alternate consumer or producer in response to a variety of events.Type: GrantFiled: September 23, 2016Date of Patent: May 26, 2020Assignee: Amazon Technologies, Inc.Inventors: Christopher Richard Jacques de Kadt, Benjamin Warren Mercier, Carlos Vara Callau, Timothy Daniel Cole, Aaron Gifford Freshwater, Sayantan Chakravorty, Allan Henry Vermeulen
