Abstract: Certain aspects of the present disclosure provide techniques for updating database records while maintaining accessible temporal history. One example method generally includes receiving a request, at a database, to select an instance of a record from the database at a specific point in time and reading the instance of the record from a snapshot of the database. The method further includes loading one or more deltas associated with the record from the database and chronologically applying the one or more deltas to the instance of the record to create the instance of the record. The method further includes returning the instance of the record, determining that the request has made a percentage of recent requests exceed a threshold for requests for most-current data and creating a new snapshot of the database.

Abstract: The disclosed embodiments provide a system that manages synchronization between a profile store and a source of truth that is used to update the profile store via a real-time link. During operation, the system obtains a first set of attributes from a profile for an entity in the profile store. Next, the system obtains a second set of attributes for the entity from the source of truth. The system then compares the first and second sets of attributes to detect and correct mismatches between the first and second sets of attributes, wherein the corrected mismatches improve subsequent use of the profile in the profile store by the set of remote offerings. Finally, the system varies a rate of comparing the first and second sets of attributes for the mismatches based on one or more execution conditions associated with the source of truth.

Abstract: The disclosed embodiments provide a system that manages synchronization between a profile store and a source of truth that is used to update the profile store. During operation, the system obtains a request to compare a first set of attributes from a profile for an entity in the profile store with a source of truth. During a period for delaying processing of the request, the system reduces a load on the source of truth by ignoring additional requests to compare the profile with the source of truth. After the period has passed, the system obtains a first set of attributes from the profile and a second set of attributes for the entity from the source of truth. The system then compares the first and second sets of attributes to detect and correct mismatches between the first and second sets of attributes.

Abstract: The disclosed embodiments relate to a system that facilitates making a copy of a profile store while the profile store is being updated. During operation, the system retrieves profiles from a profile snapshot queue, wherein the profile snapshot queue is periodically populated by accessing each profile in the profile store, and recording a snapshot of each accessed profile in the profile snapshot queue. The system then stores the profiles retrieved from the profile snapshot queue into the copy of the profile store. Next, the system retrieves updates to profiles from a live update queue, which contains a sequential list of updates to profiles in the profile store, wherein the updates are retrieved starting with a first update that occurred after the process of sequentially accessing the profiles was commenced up to a most recent update. Finally, the system uses the retrieved updates to update corresponding profiles in the copy of the profile store.

Abstract: The disclosed embodiments provide a system that manages synchronization between a profile store and a source of truth that is used to update the profile store via a real-time link. During operation, the system selects a profile for an entity in the profile store for use in verifying the synchronization between the profile store and the source of truth based on an access pattern associated with the profile store. Next, the system obtains a first set of attributes from a profile for an entity in the profile store and a second set of attributes for the entity from the source of truth. The system then compares the first and second sets of attributes to detect and correct mismatches between the first and second sets of attributes, wherein the corrected mismatches improve subsequent use of the profile in the profile store by the set of remote offerings.

Abstract: The disclosed embodiments provide a system for updating database records while maintaining accessible temporal history. The system operates by receiving a request, at a database, to select a specific instance of a record from the database at a specific point in time. In response to the request, the system reads an instance of the record from a snapshot of the database, wherein the snapshot of the database was made prior to the specific point in time. Next, the system loads one or more deltas associated with the record from the database, wherein each delta in the one or more deltas comprises the difference between a new state of the record and a prior state of the record. The system then chronologically applies the one or more deltas to the instance of the record to create the specific instance of the record. Finally, the system returns the specific instance of the record.

Abstract: The invention relates to a detection device comprising a portable recording unit (CAM) for detecting a surrounding operating area by means of a sensor, a contactless communication interface (IF) for receiving identification data, and an analyzing unit (CTR) for analyzing the identification data and for activating the recording unit (CAM) dependent on the analysis. The advantage of the invention and the embodiments of the invention over conventional recording systems is characterized, among others, in that only work steps in a definable surrounding operating area are recorded and optionally only at specific times and/or periods of times without assistance from an operator. As an expandable system, not just audio and video streams can be recorded and analyzed but also additional surroundings data, such as temperature, humidity, etc., which can be used with respect to the audio and video data.
