> 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.
