Elements in the nested dictionary will be added as it is in the output dictionary. So if the input is like [[1, 1], 2, [1, 1]], then the output will be [1, 1, 2, 1, 1] We need to flatten it to get a single dictionary where all these list elements are present as key-value pairs. 0 Shares.

Ia percuma untuk mendaftar dan bida pada pekerjaan. ‘F’ means to flatten in column-major (Fortran- style) order. Note: You can pass the PCollection as a list with beam.pvalue.AsList(pcollection), but this requires that all the elements fit into memory.. With for and update. The combination of above methods can be used to perform this task. More possibilities are here It can be ‘C’ or ‘F’ or ‘A’, but the default value is ‘C’.
