Abstract

In one respect, there is provided a method. The method can include processing a first data chunk to generate a first intermediate result. A key map can be generated based on a determination that a quantity of the key-value pairs in the first intermediate result exceeds a threshold. The key map can be generated to include keys in the first intermediate result. A second data chunk can be processed to generate a second intermediate result. The second data chunk can be processed based on the key map. The processing of the second data chunk can include omitting a key-value pair in the second data chunk from being inserted into the second intermediate result based on a key associated with the key-value pair being absent from the key map. A preview of the processing of the dataset can be generated based on the first intermediate result and the second intermediate result.
