The embodiment of the invention provides a data exporting method and device, a computer readable storage medium and an electronic device. The data exporting method comprises the steps that data is divided into multiple first-level intervals according to the distribution of values of main keys in a data table of a data source, and statistics is conducted on the distribution situation of the data of the multiple first-level intervals; according to the statistical distribution situation of the data of the first-level intervals, the multiple first-level intervals are combined to form a preset number of second-level intervals; the second-level intervals are allocated to an execution node for execution, and data of the second-level intervals is exported to a target storage module. By adopting the method, the data exporting efficiency is improved through uniform data distribution.
