  16. def stats: Statistics

    Returns the estimated statistics for the current logical plan node.

    Returns the estimated statistics for the current logical plan node. Under the hood, this method caches the return value, which is computed based on the configuration passed in the first time. If the configuration changes, the cache can be invalidated by calling invalidateStatsCache().

  17. val statsCache: Option[Statistics]

    A cache for the estimated statistics, such that it will only be computed once.

    A cache for the estimated statistics, such that it will only be computed once.
