Abstract
Embodiments of the present invention relate to a method, system and computer program product for compacting data in a distributed storage system. According to the method, a query request is received from a client, wherein the query request comprises information of a previous query request of the client. A first query result of the query request and a second query result of the previous query request are retrieved. A delta data and a first indicator are sent to the client in response to the first query result being different from the second query result, wherein the delta data is the data of the first query result excluding the data comprised in both first and second query results, and the first indicator indicates the data comprised in both the first and the second query results.
