Abstract: Computer-implemented methods and systems are provided for managing databases. Consistent with disclosed embodiments, a database system can serve configuration requests received from administration systems using an active cluster of at least two geographically separated computing clusters. Serving configuration request can include updating an active configuration database of the active cluster based on the configuration request. The system can also serve search requests received from user devices that specify a search criterion using a closest one of the geographically separated computing clusters by retrieving items satisfying the search criterion from local copies of a cache replicated across the geographically separated computing clusters. Furthermore, the system can serve transaction requests received from the user devices using the active cluster by updating an active local copy of the cache replicated in the active cluster.

Abstract: Computer-implemented methods and systems are provided for cross-cluster service provision. Consistent with disclosed embodiments, a system for cross-cluster service provision includes a first computing cluster and a second computing cluster. The first cluster includes service-providing nodes, and a first controller that collects status information concerning the service-providing nodes, the status information indicating at least one service-providing node endpoint. The second computing cluster includes service-consuming nodes, a service that receives requests for the service from the service-consuming nodes and distributes the requests among a set of specified endpoints, and a second controller that performs health checks on the specified endpoints, retrieves the status information from the first controller, and updates the set of specified endpoints based on the status information.
