SERVER-BASED MANAGEMENT FOR QUERYING EVENTUALLY-CONSISTENT DATABASE

A technique for managing access to a distributed database includes providing a server configured to receive database requests from client machines over a network. The server intelligently responds to a database request by (i) sending a first query to the distributed database at a lower consistency level to obtain a first response and (ii) conditionally sending a second query to the distributed database at a higher consistency level to obtain a second response. The server sends the second query conditionally based on whether the first response meets a plausibility condition specified in the database request. If the first response meets the plausibility condition, the server returns the first response to the client to satisfy the database request and no second query is sent. Otherwise, the server sends the second query to the distributed database and returns the second response to the client.
