I have some questions regarding the indexing and sampling API.
My aim is to implement a variant of progressive indexing as seen in this paper (link). To summarize,
I want to implement a variant of online aggregation, where an aggregate query (Like Sum, Average, etc.) is answered in real time, where the result becomes more and more accurate as Tuples are consumed.
I thought that I could maybe use a custom sampling routine to consume table samples until I have seen the whole table with no duplicate tuples.
I am not sure if I understand correctly, but if this is referring to faceted search, then then the below may be of some help.
