It will be more efficient to narrow the set of keys to evaluate than look at
all of them and evaluate the timestamp.

Subject: TimestampFilter Performance [SEC=UNOFFICIAL]



Is the TimestampFilter an efficient means of filtering results by time
ranges?  I have the option of extending the existing rowid's, currently
pre-fixed with yyyymmdd, to include hhmm also, or make use of the
TimestampFilter.  In a quick google search someone mentioned that the
TimestampFilter was inefficient is this correct?
