>Dumb text files do not preclude using a local, indexed in-memory cache.
Of course not -- but then they are not dumb anymore. You might just as well import your text file into a separate LDAP database for performance! Yep, performance debate is self-evidently over once you start talking about using a text file merely as a means of transport into a conceptual local database. Then the debate is merely one of convenience, and LDAP _without_ any kludgy export/imports wins on that front. >Just set a directory monitor trigger - when the >dumb text file changes, >reread the text file into >a new indexed cache. After the file is read, >>switch to using the new active memory cache. A fine, common design. Now "just" [a] implement it in all MTAs, so it can be part of an independent debate (remember, we are not talking about any particular anti-spam solution here, but talking about lookup architectures without regard to vendor); and [b] implement it so well that it actually scales with a huge userbase in constant flux, so well as to compete with field-hardened and scaleable databases. --Sandy -- ------------------------------------ Sanford Whiteman, Chief Technologist Broadleaf Systems, a division of Cypress Integrated Systems, Inc. mailto:[EMAIL PROTECTED] ------------------------------------ -- To Unsubscribe: http://www.ipswitch.com/support/mailing-lists.html List Archive: http://www.mail-archive.com/imail_forum%40list.ipswitch.com/ Knowledge Base/FAQ: http://www.ipswitch.com/support/IMail/
