Abstract

A query is received by a database server from a remote application server. The query is associated with a calculation model that defines a data flow model that includes a plurality of calculation nodes that each define one or more operations to execute on the database server. Thereafter, the database server dynamically determine, using at least one attribute of at least one dataset responsive to the query, that intermediate results provided by at least one of the operations specified by at least one of the nodes of the calculation model require partitioning. The database server then modifies the calculation model to partition operations on the at least one dataset based on the dynamic determination. The database server subsequently instantiates the modified calculation model so that it can be executed to generate at least one result set.
