------------------------------------
Summary: BigQueryIO.Read needs permissions to create datasets to
run queries
Key: BEAM-8458
URL: https://issues.apache.org/jira/browse/BEAM-8458
Project: Beam
Issue Type: Bug
Components: io-java-gcp
Reporter: Israel Herraiz
When using `fromQuery`, BigQueryIO creates a temp dataset to store the results
of the query.
Therefore, Beam requires permissions to create datasets just to be able to run
a query. In practice, this means that Beam requires the role bigQuery.User just
to run queries, whereas if you use `from` (to read from a table), the role
bigQuery.jobUser suffices.
BigQueryIO.Read should have an option to set an existing dataset to write the
temp results of
a query, so it would be enough with having the role bigQuery.jobUser.
