> The "memdb" VFS now allows the same in-memory database to be shared among multiple database connections in the same process as long as the database name begins with "/".<p>Ohh this is interesting -- now SQLite can function as an in-memory shared DB, as long as you have lots of readers and only one writer? IIRC WAL mode doesn't apply to in-memory DBs but the locking concurrency docs[0] seem to suggest that most of the time the one writer would hold the RESERVED+ locks and readers would hold the SHARED locks.<p>[0]: <a href="https://sqlite.org/lockingv3.html" rel="nofollow">https://sqlite.org/lockingv3.html</a>
