> 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.
