> Issue Type: Bug
> Components: SQL
> Affects Versions: 2.0.0
> Reporter: Davies Liu

> It took several minutes to plan TPC-DS Q64, because the canBroadcast() is
> super slow on large plan.
> Right now, we are considering the schema in statistics(), it's not trivial
> anymore, we should cache the result (using lazy val rather than def).
