Heh, the documentation calls out the limits. Maximum (theoretical) DB size is 281TB: https://sqlite.org/limits.html

> This particular upper bound is untested since the developers do not have access to hardware capable of reaching this limit.

> However, tests do verify that SQLite behaves correctly and sanely when a database reaches the maximum file size of the underlying filesystem (which is usually much less than the maximum theoretical database size) and when a database is unable to grow due to disk space exhaustion.
