The present teaching relates to a system, method, medium for a data system, which comprises a plurality of data centers with one read/write master server designated to handle write and consistent read requests and a plurality of read master servers designated to handle normal read requests, wherein the master servers form a ring structure and each is connected to a corresponding slave server. When a data access request is received, a read master communication unit invokes one of the plurality of read master servers in the data system if the received data access request is a normal read request, a main master communication unit invokes the read/write master server if the received data access request is either a write request or a consistent read request. When a response is received from the invoked handling master server, a response processing unit responds to the data access request based on the received response.

Method and system for high availability topology for master-slave data systems with low write traffic

System and method for location aware fine-grained multi-channel synchronization of mobile repositories along with aggregate analytic computation is disclosed. The System is able to improve upon existing systems by allowing for custom policies on synchronization to be stored and applied when data synchronization happens, these policies are persisted in the Sync Data Repository and applied during sync. The System is able to improve upon existing systems by allowing for persistent marking of states of the sync repository as Sync Points. This way data can be pulled from a sync point. The System is able to improve upon existing systems by having a computation framework that is able to push down aggregate analytics to user, these analytics are computed by analyzing data in the Sync Channel along various dimensions such as temporal, geo.
