SPLIT PROCESSING PATHS FOR A DATABASE CALCULATION ENGINE
First Claim
1. A computer program product comprising a machine-readable medium storing instructions that, when executed by at least one programmable processor, cause the at least one programmable processor to perform operations comprising:
- receiving, at a dynamic split node defined within a calculation model, data being operated on by a calculation plan generated based on the calculation model;
applying a partition specification to one or more reference columns in a table containing at least some of the received data, the applying causing the table to be split such that a plurality of records in the table are partitioned according to the partition specification;
setting a separate processing path for each partition; and
continuing execution of the calculation plan using the separate processing paths, each of the separate processing paths being assigned to a processing node of a plurality of available processing nodes.

Abstract
A dynamic split node defined within a calculation model can receive data being operated on by a calculation plan generated based on the calculation model. A partition specification can be applied to one or more reference columns in a table containing at least some of the received data. The applying can cause the table to be split such that a plurality of records in the table are partitioned according to the partition specification. A separate processing path can be set for each partition, and execution of the calculation plan can continue using the separate processing paths, each of which can be assigned to a processing node of a plurality of available processing nodes.
