Abstract:
The subject matter of the disclosure is embodied in a method that includes identifying a user-list which is based on owned or permissioned data, wherein the user-list is associated with a corresponding owner database. The method also includes providing an application programming interface (API) configured to communicate with the owner database, and receiving, from the owner database through the API, metadata related to the user-list. The metadata at least includes data describing a category for the user-list. The method further includes storing in a searchable database a user-list identifier corresponding to the user-list and the associated metadata, and providing a user-interface that includes the user-list identifier and the corresponding associated metadata. The user-interface is configured to receive one or more management instructions related to the user-list from a user-list subscriber.
Abstract:
Scalable systems and methods for delivering ordered data updates from a plurality of data sources are provided. A described method includes receiving, a data update from a data source and assigning a global sequence identifier and a previous global sequence identifier to the data update. The global sequence identifier indicates a position of the data update in a sequence of data updates received from a plurality of data sources. The previous global sequence identifier is a global sequence identifier assigned to a preceding data update received from the same data source. The method further includes determining whether the preceding data update from the same data source has been delivered by comparing the previous global sequence identifier with a low water mark. The low water mark is an upper bound on a range of global sequence identifiers associated with data updates that have been delivered.
