I have a BigQuery table set up with a Cloud BigTable external data source. This works fine, and I'm able to run queries joining my BigTable data to some of my other BigQuery data. However, when I run too many queries against this table simultaneously, I get the following error:
Error encountered during job execution:
Exceeded rate limits: too many concurrent queries that read Cloud Bigtable data sources for this project. For more information, see https://cloud.google.com/bigquery/troubleshooting-errors
I can't find any documentation about the limits on concurrent queries on the linked page or on the BigQuery Quotas and Limits page. I'm not running that many queries here - max 10 at a time. Has anyone run into this before who knows what the actual concurrent query limit is?
