I am getting Null values in propsmap column with same code used, can you pl explain why so

[@user-nt7lg6wz1o]

But,
What is the actual advantage of using a maptype?
Can you explain.
Thanks in advance

[@mohammedluqman8757]

If any of the column has a null value, entire record is being ignored. How to fix this?

[@sai.k2141]

Instead of passing key as hair directly as separate column, is it possible to pass the key dynamically as separate column.

When we read Json objects by default it is being read as MapType. Why do we explicitly use from_json function ?
