Flatten List in Python An Introduction. A List is considered as one of the most flexible data structures in the Python programming language. On the other hand, a two-dimensional list, or 2D List, which is generally termed as a list of lists, is an object of a list where each element is a list itself.z is a JSON array. Usage Notes. The FLATTEN function is useful for flexible exploration of repeated data. To maintain the association between each flattened value and the other fields in the record, the FLATTEN function copies all of the other columns into each new record. A very simple example would turn this data (one record):

Regards, Angel Petrov Progress TelerikThis example walks through how to use Java Maps and Lists using Jackson and MongoDB classes in Talend Studio to handle the richer JSON document structure.

The result looks great. All nested values are flattened and converted into separate columns. If you don't want to dig all the way down to each value use the max_level argument. With the argument max_level=1, we can see that our nested value contacts is put up into a single column info.contacts.. pd.json_normalize(data, max_level=1)When a MongoDB document contains a nested document (structure) it is faithfully encoded as a nested structure field. If the sink connector does support only flat structure it is possible to flatten the internal structure into a flat one with a consistent field naming. To enable this feature the option flatten.struct must be set to true.
