Using the synchronous google.api_core.retry.Retry with asynchronous calls may lead to unexpected results. Please use google.api_core.retry_async.AsyncRetry instead.

Environment details

• OS type and version: macOS Ventura 13.0
• Python version: 3.11.2
• pip version: pip 22.3.1
• google-cloud-bigquery-storage version: 2.23.0

Steps to reproduce

1. Create read session with using BigQueryReadAsyncClient
2. Get warning that synchronous retry is used instead of asynchrounous one

Code example

 def create_read_session(
    bq_table_path: str,  # in project.dataset.table format
):
    project_id, dataset_id, table_id = bq_table_path.split(".")

    client = BigQueryReadAsyncClient()

    read_sessions_type = types.ReadSession(
        table=f"projects/{project_id}/datasets/{dataset_id}/tables/{table_id}",
        data_format=types.DataFormat.AVRO,
        read_options=types.ReadSession.TableReadOptions(
            selected_fields=[column.name for column in dataclasses.fields(row_type)],
            row_restriction=row_restriction,
        ),
    )
    create_read_session_request = types.CreateReadSessionRequest(
        parent=f"projects/{project_id}",
        read_session=read_sessions_type,
        max_stream_count=1,
    )

    read_session = await client.create_read_session(request=create_read_session_request)

    return read_session

read_session = create_read_session("project.dataset.table") # Pass real table info here

Potential cause/solution

In the file google/cloud/bigquery_storage_v1/services/bigquery_read/async_client.py the following import is made:

from google.api_core import retry as retries

and I believe it should be:

from google.api_core import retry_async as retries

This seems like an issue in other async clients too (eg. BigQueryWriteAsyncClient)

Also here was similiar issue in googleapis/python-firestore: https://github.com/googleapis/python-firestore/issues/793

This issue was transferred from python-bigquery-storage to google-cloud-python as part of the work for https://github.com/googleapis/google-cloud-python/issues/10991.
