> We needed a filter that allows us to randomly include rows. I will attach a
> patch with a simple Filter that is able to do this.
> For example, if you wish to do a scan but only want 1/4 of all values
> (randomly distributed), you can use: new RandomRowFilter(0.25f)
> I just wanted to share this Filter with you. It's up to you if you want to
> include it in the codebase.
