Since this doesn’t touch a real problem of mine I’m somwhat uncertain, if it is even worth to be asked here. However maybe some of you would like to share your opinion on that.
In general I have to admit, that ‘better’ means anything and nothing at all at the same time. So I probably should be more specific, but I tried not to overflow the topic. In a regular hosted environment on one of those cheap webhosters (like Dreamhost), with around 1000 articles in Joomla, a couple of users and a few hundreds visitors a day, would a SQLite database with a persistent connection (sqlite_popen) perform noticeable faster than the MySQL equivalent (with the TCP/IP overhead etc.)?
Or in short: Would it be wise to call Joomla to support SQLite?
I have never used sqlite on a website, but I have used it extensively for other purposes and I quite like it. The truth is, you won’t know till you try. If you try, I reccomend creating a db abstraction layer first so that you can easily swap in other db’s.
The downside to sqlite is that it’s not really meant to be a multi user database. If you rarely write to the db, but do lots of reading, sqlite will probably be fine. If you find that you need multiple processes writing to the same db, I believe sqlite uses file level locking to maintain database consistency.. So, if all you’re tables are in the same file, you’ll lock the whole file while it’s being written to even if another process wants to modify a completely different table.
In my opinion it’s not the big multi user databases of the world that should be worried about competition from sqlite… It’s all the regular files out there (and there custom file formats) that applications create and use that should be shaking in their boots about sqlite…
