Zhenhua Wang updated SPARK-17129:
---------------------------------
Description: I upgrade this JIRA as an umbrella ticket, because there are a
few tasks found and needed to be done here. (was: We need to support
generation/storing/loading partition-level statistics,
and use stats from single/multiple partitions (after partition pruning) to
estimate cardinality.)
> Support statistics collection and cardinality estimation for partitioned
> tables
