How does SQLite handle concurrency?

Question

SQLite has a lock table that helps locking the database as late as possible during a write operation to ensure maximum concurrency. The initial state is UNLOCKED, and in this state, the connection has not accessed the database yet. 30 окт. 2010 г.

Can SQLite handle multiple users?

Yes SQLite can support multiple users at once. It does however lock the whole database when writing, so if you have lots of concurrent writes it is not the database you want (usually the time the database is locked is a few milliseconds - so for most uses this does not matter).

How many concurrent connections can SQLite handle?

The default limit is 1,024.

Is SQLite multithreaded?

In serialized mode, SQLite can be safely used by multiple threads with no restriction.

How much traffic can SQLite handle?

The amount of web traffic that SQLite can handle depends on how heavily the website uses its database. Generally speaking, any site that gets fewer than 100K hits/day should work fine with SQLite. The 100K hits/day figure is a conservative estimate, not a hard upper bound.
