Abstract
Methods of generating filters automatically from data processing jobs are described. In an embodiment, these filters are automatically generated from a compiled version of the data processing job using static analysis which is applied to a high-level representation of the job. The executable filter is arranged to suppress rows and/or columns within the data to which the job is applied and which do not affect the output of the job. The filters are generated by a filter generator and then stored and applied dynamically at a filtering proxy that may be co-located with the storage node that holds the data. In another embodiment, the filtered data may be cached close to a compute node which runs the job and data may be provided to the compute node from the local cache rather than from the filtering proxy.
