-------------------------------
Summary: Long execution delay when using DirectRunner to read from
BigQuery Table
Key: BEAM-4548
URL: https://issues.apache.org/jira/browse/BEAM-4548
Project: Beam
Issue Type: Bug
Components: io-java-gcp, runner-direct
Affects Versions: 2.4.0
Reporter: Brian Foo
Assignee: Chamikara Jayalath
When using DirectRunner to execute a simple select query against a BigQuery
table that contains 100 rows, the pipeline stalls for about 5 minutes. The
BigQuery UI can run the same query in under 2 seconds.
A similar issue was reported here:

I ran a thread dump using Visual M seems like the main thread was in a state of
backoff:
