Abstract

A join operation between split data tables includes providing value IDs. For each of the value IDs, a unique global ID may be associated with the value ID when the actual value represented by the value ID occurs among actual values comprising the second attribute of the second partition. For each identified unique global ID, the identified unique global ID may be paired with a document ID of a data record contained in a second partition stored at the second server in which the actual value in the data record is represented by the value ID associated with the identified unique global ID.
