> Key: KUDU-3033

> Project: Kudu
> Issue Type: New Feature
> Components: cfile, perf, tablet
> Reporter: LiFu He
> Priority: Major
> Labels: performance, roadmap-candidate
>
> It's possible to add min/max values for the non-primary key columns in the
> metadata of diskrowset/datablock, and then we can skip decoding/evaluating
> the unnecessary diskrowset/datablock while scanning. Just like the "compute
> stats" feature on impala, and the only difference is that kudu supports
> updates. So, the min/max values should be invalid if the columns that have
> deltas while scanning.
