Partitioned key-value stores with one-sided communications are provided for secondary global key lookup by range-knowledgeable clients. A secondary global lookups is performed in a partitioned key-value store by receiving a request from an application for a secondary global key; accessing metadata to identify a first server storing the secondary global key; instructing the identified first server to store a first value corresponding to the requested secondary global key into a memory address of the client; and returning program control to the application, wherein the first server identifies a primary key corresponding to the requested secondary global key and instructs a second server storing the corresponding primary key to store a second value corresponding to the primary key into the memory address of the client. The second server stores the second value corresponding to the primary key into the first memory address of the client.
