bigquery 存储 API 在创建读取会话时挂起

Question

I can use the BigQuery Storage API to read the sample public dataset. But when I created my own dataset, it got hand at create read session: client.create_read_session . The problem still persists even I granted the public read access to the dataset.

The problem still persists even I granted the public read access to the dataset.

Answer 1

I had the same issue with client.create_read_session like below

From public dataset(project_id: bigquery-public-data):

• Fine

From my private dataset 'A':

• Error(Hang) with no retry option
• Error(503:Service Unavailable) with retry=None

From my private dataset 'B':

• Fine again

hmm...

And I carefully started looking at each schema of A/B, and realized that EU/US region was OK but Seoul, S.Korea(asia-northeast3) might not be supported for now.

I guess that your region might not be supported just like my situation.
