Bigquery streaming TableRow size limit
Hey all, The TableRow size limit is 1mb when streaming into bigquery. To prevent data loss, I’m going to implement a TableRow size check and add a fan out to do a bigquery load job in case the size is above the limit. Of course this load job would be windowed. I know it doesn’t make sense to stream data bigger than 1mb, but as we’re using pub sub and want to make sure no data loss happens whatsoever, I’ll need to implement it. Is this functionality any of you would like to see in BigqueryIO itself? Or do you think my use case is too specific and implementing my solution around BigqueryIO will suffice. Thanks for your thoughts, Wout

Having data ingestion work without needing to worry about how big the blobs are would be nice if it was automatic for users.

Re: Bigquery streaming TableRow size limit
I'm a bit worried about making this automatic, as it can have unexpected side effects on BigQuery load-job quota. This is a 24-hour quota, so if it's accidentally exceeded all load jobs for the project may be blocked for the next 24 hours. However if the user opts in (possibly via .a builder method), this seems like it could be automatic.

Re: Bigquery streaming TableRow size limit
I would rather not have the builder method and run into the quota issue then require the builder method and still run into quota issues.

Re: Bigquery streaming TableRow size limit
Generally I would agree, but the consequences here of a mistake are severe. Not only will the beam pipeline get stuck for 24 hours, _anything_ else in the user's GCP project that tries to load data into BigQuery will also fail for the next 24 hours. Given the severity, I think it's best to make the user opt into this behavior rather than do it magically.

Re: Bigquery streaming TableRow size limit
Thanks for your thoughts. Also, I’m doing something similar when streaming data into partitioned tables. From [1]: “ When the data is streamed, data between 7 days in the past and 3 days in the future is placed in the streaming buffer, and then it is extracted to the corresponding partitions.” I added a check to see if the event time is within this timebound. If not, a load job is triggered. This can happen when we replay old data. Do you also think this would be worth adding to BigqueryIO? If so, I’ll try to create a PR for both features.

Re: Bigquery streaming TableRow size limit
This sounds a bit more specific, so I wouldn't add this to BigQueryIO yet.
