Abstract
Various examples are directed to systems and methods for utilizing local identifiers in a distributed database system. A database management system server may receive first execution unit data describing a first execution unit of a first database query. The first execution unit data may comprise first operand data describing a set of operands for the first execution unit. The database management system server may determine that the first operand data describes at least one operand from a first partition and at least one operand from a second partition. The database management system server may generate a first set of local identifiers describing rows at the first partition and a first set of local identifiers describing rows at the second partition. The database management system server may execute the first execution unit based at least in part on the first set of local identifiers describing rows at the first partition and the first set of local identifiers describing rows at the second partition.
