                 URL: https://issues.apache.org/jira/browse/FLINK-5859

          Issue Type: New Feature

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.
