If your SQLite DB is being accessed locally by the webserver, then there is no reason to worry about consistency issues due to the webserver's network activity, provided that your application can handle the access delay issues that arise when multiple threads may attempt overlapping DB operations. If you are happy with the performance and the number of clients is not likely to grow much, SQLite could be a good solution. What Jay and others warn about is that SQLite is not designed for concurrent DB operations. Also, have its file store be accessed over a network from SQLite code running remotely is a formula for database corruption. But it looks like you are not doing that.

Your difficulty most likely arises from how your call into those APIs is done, which you have not shown. To get help, you will need to show more.

Hello. And, excuse my.
