Currently there are no asynchronous Python SDK examples within the documentation.

This makes the API very difficult to use as it's not always as simple as just adding a few 'awaits' to the synchronous examples.

We need a page for Python that's similar in scope and style to https://docs.couchbase.com/java-sdk/current/howtos/concurrent-async-apis.html so that users have a starting point for using the async API, even if it does not cover everything.

In case it's at all useful, below is a simple example of using the async API to perform a N1QL query:

import asyncio

from acouchbase.cluster import Cluster

from couchbase_core.cluster import PasswordAuthenticator

async def main():

    conn_str = 'couchbase://10.143.201.101'

    cluster = Cluster(conn_str, authenticator=PasswordAuthenticator('Administrator', 'password'))

    await cluster.on_connect()  # This will wait until the cluster is connected

    res = cluster.query('select * from `test` limit 1;')

    async for row in res:

        print(row)

if __name__ == "__main__":

    asyncio.run(main())
