> 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.
