AsyncIO bridge to the standard sqlite3
module for Python 3.5+
aiosqlite is compatible with Python 3.5 and newer. You can install it from PyPI with the following command:
$ pip install aiosqlite
aiosqlite replicates the standard sqlite3
module, but with async versions
of all the standard connection and cursor methods, and context managers for
automatically closing connections:
async with aiosqlite.connect(...) as db: await db.execute('INSERT INTO some_table ...') await db.commit() cursor = await db.execute('SELECT * FROM some_table') async for row in cursor: ...
aiosqlite allows interaction with SQLite databases on the main AsyncIO event loop without blocking execution of other coroutines while waiting for queries or data fetches. It does this by using a single, shared thread per connection. This thread executes all actions within a shared request queue to prevent overlapping actions.
Connection objects are proxies to the real connections, contain the shared execution thread, and provide context managers to handle automatically closing connections. Cursors are similarly proxies to the real cursors, and provide async iterators to query results.
