----------------------------------
Summary: Statistics of logical plan is super slow on large query
Key: SPARK-16163
URL: https://issues.apache.org/jira/browse/SPARK-16163
Project: Spark
Issue Type: Bug
Components: SQL
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).
