I'm trying to test VerdictDB using TPC-H. However, I was wondering if I can create a sample table hashing on an expression of a column? For example,
CREATE SCRAMBLE tpch1g.lineitem_scramble FROM tpch1g.lineitem HASH ON year(l_shipdate) BLOCKSIZE 100
Hash scrambling only supports hashing on a column currently.
How about multiple columns?
It only works on a single column at the moment.
Got it! Thanks!
