Abstract
A computer-implemented method for improving performance of data processing with nullable schema information by using a data processing framework is presented. The method includes reading, by the processor, data from one or more blocks forming a column, where the data is stored in a database including the one or more blocks and determining, by the processor, whether any row in each block of the one or more blocks includes null data. The computer-implemented method further includes executing, by the data processing framework, optimized code if the block does not include null data and executing, by the data processing framework, non-optimized code if the block includes null data.
