Hi, I have read some notes on ORC files in Hive and indexes. The document describes in the indexes but makes reference to statistics Indexes | | | | | | | | | | | IndexesIndexes ORC provides three level of indexes within each file: file level - statistics about the values in each column across the entire file | | | | View on orc.apache.org | Preview by Yahoo | | | | |
I am confused as it is mixing up indexes with statistics. Can someone clarify these. Thanks
