Thanks Prasanth. Does it also mean that a query reading nested.k column
will invariably read nested.v as well even if nested.v column in not used

Hi all,
I have few questions with regards to nested columns in Hive.

Hi
ORC stores nested fields as separate columns. For example: The following table
create table orc_nested (key string, nested structk:string,v:string, zip
long) stored as orc;
will be flattened and stored as separated columns like below
key, nested, nested.k, nested.v, zip
you can have a look
