摘要：Various examples are directed to systems and methods for utilizing localidentifiers in a distributed database system. A database management system server mayreceive 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 ofoperands for the first execution unit. The database management system server maydetermine that the first operand data describes at least one operand from a firstpartition and at least one operand from a second partition. The database managementsystem server may generate a first set of local identifiers describing rows at the firstpartition and a first set of local identifiers describing rows at the second partition. Thedatabase management system server may execute the first execution unit based at leastin part on the first set of local identifiers describing rows at the first partition and thefirst set of local identifiers describing rows at the second partition.
