Subject Scan vs Filter performance.
Date Mon, 28 Sep 2015 16:19:02 GMT
Hi all:

I would like to perform a range scan on a table, tweaking the definition of
what goes into a particular key range. One way I can think of is writing a
filter on the key, and that would work fine. But I think it would be slow
compared to a scan / seek custom iterator. How does the underlying login
works? Does Filter goes through all records, or since is sorted follows the
same underlying logic as a scan? Would a custom iterator perform better?

Thank you for your time,

Moises
