Async vs Sync¶
On previous versions of GQL, the code was sync only , it means that when you ran execute on the Client, you could do nothing else in the current Thread and had to wait for an answer or a timeout from the backend to continue. The only http library was requests, allowing only sync usage.
From the version 3 of GQL, we support sync and async transports using asyncio.
With the async transports, there is now the possibility to execute GraphQL requests asynchronously, allowing to execute multiple requests in parallel if needed.
If you don’t care or need async functionality, it is still possible, with async transports, to run the execute or subscribe methods directly from the Client (as described in the Basic Usage example) and GQL will execute the request in a synchronous manner by running an asyncio event loop itself.
This won’t work though if you already have an asyncio event loop running. In that case you should use Async Usage
