Techniques are described for data redistribution. Embodiments store a first set of receiver location identifiers mapped to a document identifier and assigned to a first set of receiver locations storing relational data referencing the document identifier. Embodiments store a second set of receiver location identifiers mapped to the document identifier and assigned to a second set of receiver locations storing document data corresponding to the document identifier referenced by the relational data. Sender index keys are received separately from the relational data and the document data, the sender index keys referencing the document identifier and containing sender location identifiers. Embodiments determine, from the first set of receiver location identifiers and the second set of receiver location identifiers, which receiver location identifiers are mapped to the document identifier referenced by the sender index keys. The sender location identifiers are then replaced with the determined receiver location identifiers.

Techniques are described for data redistribution in a database system. Embodiments store a first set of receiver location identifiers mapped to a document identifier, the first set of receiver location identifiers assigned to a first set of receiver locations storing relational data referencing the document identifier. Embodiments further store a second set of receiver location identifiers mapped to the document identifier, the second set of receiver location identifiers assigned to a second set of receiver locations storing document data corresponding to the document identifier referenced by the relational data. Sender index keys are received separately from the relational data and the document data, the sender index keys referencing the document identifier and containing sender location identifiers. Embodiments determine, from the first set of receiver location identifiers and the second set of receiver location identifiers, which receiver location identifiers are mapped to the document identifier referenced by the sender index keys. The sender location identifiers are then replaced with the determined receiver location identifiers.
