Maria commented on SPARK-17129:
-------------------------------

[~ZenWzh], I happen to work with large number of partitioned tables where each 
partition itself is very large and each table has lots of partitions. At the 
same time, most queries use data from a limited number of partitions. Hence, 
I'm interested in collecting statistics on a per-partition basis. For example, 
I need to be able to issue ANALYZE TABLE table PARTITION xxx COMPUTE STATISTICS 
statement. I have made a change to support that in Spark and would like to 
submit a PR. Would that be OK?
