I think performance can be tested only by actual testing on live data. I'll code my application accordingly so that I can replace Sqlite specfic code with something else in case I run into major problems. -- Thanks again, Asif - To unsubscribe, send email to [EMAIL PROTECTED] -

Please reply assuming I tend to come up optimized db & query designs - keeping in view general rules for database/query optimizations. SQLite is not optimised for large datasets. Data recovery will work, as advertised, in the general case including large datasets, but the memory footprint of the library increases as the size of the database grows. Consider using larger pages than the default 1024 bytes to limit the number of pages SQLite must track. Other than that, the performance should degrade predictably with increasing datasets, given that SQLite uses the same BTree(+) based algorithms used by most database engines. -- Thanks again and best regards, Asif - To unsubscribe, send email to [EMAIL PROTECTED] - -- /"\ \ /ASCII RIBBON CAMPAIGN - AGAINST HTML MAIL X - AGAINST MS ATTACHMENTS / \ - To unsubscribe, send email to [EMAIL PROTECTED] -

I'm not sure if you would qualify this as hype, but sqlite is used in many end-user products, ranging from operating systems (OS X), webbrowsers (Firefox), embedded systems like PDA's, mp3 players etcetera. These are all enviroments where the users 1) aren't especially careful 2) aren't willing or able to handrecover a database. They even don't know it's there. -- ( Kees Nuyt ) c[_] - To unsubscribe, send email to [EMAIL PROTECTED] -
[sqlite] Recovery After Crash
Hi Everybody, I have just joined this mailing list as Sqlite looks like a good software solution to my needs. What I need right now is RE-assurance of "crash-recovery" that is mentioned on your front page. So, I would be thankful if you experts would give me an "accurate" and fair picture of the crash-recovery aspects of SQLite - without any hype. -- Best regards, Asif - To unsubscribe, send email to [EMAIL PROTECTED] -
