Will SQLite performance degrade if the database size is greater than 2 gigabytes?
Last year when I checked about SQLite on their web site, the recommended SQLite database size was 2 gigabytes. But now, I could not find that recommendation again.
So has anyone tried to work with an SQLite database that is bigger than 2 gigabytes using latest version of it? How well did SQLite perform?
P.S: I would like to make a mobile application that requires big database (for example storing Wikipedia articles) that works locally.
Answer
There is no 2 GB limit.
SQLite database files have a maximum size of about 140 TB.
On a phone, the size of the storage (a few GB) will limit your database file size, while the memory size will limit how much data you can retrieve from a query. Furthermore, Android cursors have a limit of 1 MB for the results.
The database size will, by itself, not affect your performance. Your queries will be fast as long as they do not access more data than fits into the DB's page cache (2 MB by default).
