Does SQLite3 handle concurrent access by multiple processes?

So you might say SQLite safely handles concurrent access by multiple processes writing to the same DB simply because it doesn't support it! You will get SQLITE_BUSY or SQLITE_LOCKED for the second writer when it hits the retry limitation. 30 окт. 2010 г.


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.

How many concurrent connections can SQLite handle?

The default limit is 1,024.

Can SQLite handle concurrent writes?
