WL#2252: Automatic co-location of related rows

Affects: Benchmarks-3.0   —   Status: Un-Assigned   —   Priority: Medium

Typical setup:

Holder
  holder_id int autoincrement primary key
  holder_name varchar(255)

Account
  account_id int autoincrement primary key
  holder_id int REFERENCES holder(holder_id)

I.e. each account has a holder.
The idea is to change to schema slightly into

Account
  account_id identity primary key
  holder_id int REFERENCES holder(holder_id)

Idea:
  account_id is a generated value that will hash into same
  fragment as holder_id
