--------------------------------
What is about the current status? It is a very useful feature for fast scan.

> Do we have a plan to add index on any column [not primary column] ? Currently
> kudu does not have btree or inverted index on columns. In this case if a
> query wants to filter a column then kudu has to scan all datas in all
> rowsets.
> For example, select * from table where salary > 10000 and age < 40, the bloom
> filter or min max index will have no effect, kudu has to scan all datas in
> all row sets. But if kudu has inverted index, then it will be much faster.
