Re: Large range query stops using indexes
How are index scans a "random read"? Traditionally, indexes are normally B-Trees, unless specified otherwise. (I'm pretty sure that my index in question is a B-Tree).
...of which, I envision the query should an index for range scans as follows: Locate low value, locate high value, parse all in-between branches and return all leaves. It seems not to be doing that. Sigh.
