Abstract
The disclosed embodiments relate to a system that uses colocation hints to facilitate storing data blocks in a distributed data storage system, which includes a plurality of data centers. During operation, the system receives a write request from a client to write a data block to the distributed data storage system, wherein the write request includes a colocation hint that identifies a colocation group associated with the data block. In response to the write request, the system uses the colocation hint to identify one or more data centers associated with the colocation group. Next, the system writes copies of the data block to the one or more identified data centers. In this way, the system situates copies of data blocks associated with the colocation group in the same data centers when possible.
