Can multiple programs access the same SQLite database?

Can multiple processes access SQLite?

SQLite allows multiple processes to have the database file open at once, and for multiple processes to read the database at once. When any process wants to write, it must lock the entire database file for the duration of its update. But that normally only takes a few milliseconds.

Does SQLite support concurrent access?

Usually, SQLite allows at most one writer to proceed concurrently. The BEGIN CONCURRENT enhancement allows multiple writers to process write transactions simultanously if the database is in "wal" or "wal2" mode, although the system still serializes COMMIT commands.

What are the limitations of SQLite?

An SQLite database is limited in size to 281 terabytes (248 bytes, 256 tibibytes). And even if it could handle larger databases, SQLite stores the entire database in a single disk file and many filesystems limit the maximum size of files to something less than this.

Why is SQLite not good for production?

Long answer: It is said you can't use SQLite in production because it doesn't support concurrency (no more than one user can be writing to the database at the same time) and it can't scale.
