Hi,
We need to query deeply nested Json structure. However query is on a single
field at a nested level such as mean, median, mode.
I am aware of the sql explode function.
df = df_nested.withColumn('exploded', explode(top))
But this is too slow.
Is there any other strategy that could give us t
I would love to be told otherwise, but I believe your options are to either
1) use the explode function or 2) pre-process the data so you don't have to
explode it.

Have you checked out this blog post?

Shows tools and tips on how to work with nested data. You can access data
through `field1.field2.field3` and such with JSON.
