A record within a destination virtual file is generated on a destination node of a distributed data storage system. The record comprises (i) a link directed to a partition of a source virtual file stored on a source node and (ii) partition criteria characterizing the partition. The source virtual file is mapped to a chain of linked pages stored in a page buffer of the distributed data storage system and the partitioning criteria is used by at least one of the source node and the destination node to identify data associated with the partition. A request is later received at the destination node to access data defined by the destination virtual file. Data is provided, in response to the request, from the partition of the source virtual file stored on the source node using the link and the partitioning criteria. Related apparatus, systems, techniques and articles are also described.
