Matt McCline commented on HIVE-5570:
------------------------------------
Virtual columns in the Partition (i.e. Map operator) for PTF:
BLOCKOFFSET ("BLOCK__OFFSET__INSIDE__FILE")
FILENAME ("INPUT__FILE__NAME")
First PTF query from ptf.q is:
select
p_mfgr,
p_name,
p_size,
rank()
over (partition by p_mfgr order by p_name) as r,
dense_rank()
over (partition by p_mfgr order by p_name) as dr,
sum(p_retailprice)
over (partition by p_mfgr order by p_name rows between unbounded preceding
and current row) as s1
from noop(on partorc
partition by p_mfgr
order by p_name
);
> Handle virtual columns and schema evolution in vector code path
