Yes, it's a tautology - if you cared about performance, you'd use ORC, because 
ORC is the fastest format.

And doing performance work to support folks who don't quite care about it, is 
not exactly "see a need, fill a need".

Literally years have gone by since the feature came into Hive. Though it might 
have crept up on you - if Vectorization had been enabled by default, it 
would've been immediately obvious.

HIVE-9937 is so old, that I'd say the first line towards Text vectorization 
came in in Q1 2015.

In the current master, you can get a huge boost out of it - if you want you can 
run BI over 100Tb of text.

You've got it backwards - ORC was designed to support those features.

Parquet could be following ORC closely, but at least the Java implementation 
hasn't.
