Abstract

A method, a computer program product, and a system for scheduling a first query execution plan for executing a first query for accessing first data sets of data of a relational database system (RDBS) and a second query execution plan for executing a second query for accessing second data sets of the data. The data is divided into data blocks of data sets of the data, wherein metadata of the RDBS comprises respective information about at least one property of the data sets of a respective data block of the data blocks. The scheduling may be performed on the basis of an examination if there is a common partition between a first partition of data blocks which may fulfill a first condition according to the first query and a second partition of data blocks which may fulfill a second condition according to the second query.
