+1 for this feature. Additionally, It is described in your draft that "specify the bloom columns using table properties", I do recommend that for the first phrase, we should not use this information from table properties while querying.
We can store the index information in blocklet（or page) level and use it when we process this blocklet(or page). After this, later we can automatically decide to build the corresponding index for some columns or some pages on the fly without the user's help. -- Sent from: http://apache-carbondata-dev-mailing-list-archive.1130556.n5.nabble.com/
