Abstract: At a machine learning service, a determination is made that an analysis to detect whether at least a portion of contents of one or more observation records of a first data set are duplicated in a second set of observation records is to be performed. A duplication metric is obtained, indicative of a non-zero probability that one or more observation records of the second set are duplicates of respective observation records of the first set. In response to determining that the duplication metric meets a threshold criterion, one or more responsive actions are initiated, such as the transmission of a notification to a client of the service.

Abstract: In response to determining that continuous data protection is to be enabled for a particular table of a database service, a service component verifies that automated transmission of change records of the table to a log-structured journal has been configured. A given change record comprises a before-image and an after-image associated with a committed database write, and is assigned a unique sequence number. In response to a determination to restore the table as of a specified point in time, a restore record set is identified from the journal with respect to a selected snapshot of the table. The restore record set includes change records which are not represented in the snapshot and are to be represented in the restored table. A restore result table is created using the selected snapshot and the restore record set.

Abstract: A system receives a first indication associated with a first device picking up a package and transmits a first instruction to the first device to travel to a location associated with transferring the package to a second device. The system may transmit a second instruction to the second device to travel to the location to receive the package from the first device. The system receives a second indication associated with the package being transferred from the first device to the second device at the location. One or more third devices may meet at the location to transfer packages to the second device. In some instances, the location may be determined based at least in part on a current location of the first device and/or a current location of the second device.

Abstract: Systems and methods to reduce aerodynamic drag and/or affect flight characteristics of an aerial vehicle may include adjustable fairings associated with one or more components of the aerial vehicle. The adjustable fairings may be coupled to and at least partially surround a motor, propulsion mechanism, motor arm, strut, or other component of an aerial vehicle. In addition, the adjustable fairings may be passively movable between two or more positions responsive to airflow around the fairings, and/or the adjustable fairings may be actively moved between two more positions to affect flight characteristics. Further, the adjustable fairings may include actuatable elements to alter a portion of an outer surface of the fairings to thereby affect flight characteristics. In this manner, adjustable fairings associated with various components of an aerial vehicle may reduce aerodynamic drag and/or may improve control and safety of an aerial vehicle.

Abstract: Online block parsing techniques are performed that use anchor tokens. When a log entry of a log stream is received, the log entry may be tokenized into an ordered series of log units. The log units may be matched with anchor tokens in previously initialized log templates to determine a matching log template. A log template based on the matching log template may be provided with the tokenized log entry to a destination for a parsed version of the log stream.

Abstract: Techniques are described for providing customizable sign-on functionality, such as via an access manager system that provides single sign-on functionality and other functionality to other services for use with those services' users. The access manager system may maintain various sign-on and other account information for various users, and provide single sign-on functionality for those users using that maintained information on behalf of multiple unrelated services with which those users interact. The access manager may allow a variety of types of customizations to single sign-on functionality and/or other functionality available from the access manager, such as on a per-service basis via configuration by an operator of the service, such as co-branding customizations, customizations of information to be gathered from users, customizations of authority that may be delegated to other services to act on behalf of users, etc., and with the customizations that are available being determined specifically for that service.

Abstract: A method for a first network device involves transmitting, to one or more second network devices, an uplink message that includes an indication of a receive window time interval, and may also include an indication of a request for a downlink message. The method also involves initiating a scheduled receive mode that causes the first network device to transition the first network device to a first power state, and perform a receive window procedure after the receive window time interval has elapsed. The receive window procedure includes transitioning the first network device to a second power state and listening for the downlink message for a duration of time. The method further involves determining that an expiration condition has been met while the first network device is in the scheduled receive mode. Additionally, the method involves terminating the scheduled receive mode upon determining that the expiration condition has been met.

Abstract: Approaches are described for image signal processor day-night detection. An exemplary approach for a camera with an infrared light source involves determining a brightness value for image data based on an average luma value for the image data, determining white balance data for the first image data, and determining, based on the white balance data for the image data and white balance data for the infrared light source, a deviation value for the image data. A transition from night mode to day mode can be effected based on comparing the brightness value for the image data to a first threshold, and comparing the deviation value for the image data to a second threshold.

Abstract: Methods, systems, and computer-readable media for distributed transactions across multiple consensus groups are disclosed. A distributed transaction system comprises a proposer and a plurality of consensus groups, including a first consensus group comprising a first plurality of members and a second consensus group comprising a second plurality of members. The proposer proposes a transaction to at least a portion of the first consensus group and at least a portion of the second consensus group. A majority of the members in the first consensus group agree to perform the transaction, where the transaction is selected from a plurality of proposed transactions involving the first consensus group. A majority of the members in the second consensus group also agree to perform the transaction. The members of the first and second consensus groups perform the transaction to update a plurality of stored replicas.

Abstract: A thread of a storage server determines that a command to modify a reservation record which comprises access permissions of an object stored at the server has been received. A version of the record is stored in an in-memory cache. The thread acquires a first lock associated with the record in exclusive mode, and a second lock in shared mode. The thread reads the cached version, constructs a modified version indicated in the command, and releases the second lock without updating the cache. After entries representing the modified version are stored in an operations journal, the thread acquires the second lock in exclusive mode and updates the cache. The thread then releases both locks. An indication that the command has succeeded is provided without verifying that the second version is stored at a metadata store.
