> Many data sources are partitionable storage, e.g. HDFS, Druid. And many 
> queries just need to read a small subset of the total data. We can use 
> partition information to prune or skip over files irrelevant to the user’s 
> queries. Both query optimization time and execution time can be reduced 
> obviously, especially for a large partitioned table.
