------------------------------------
Summary: Beam SQL should support BigQuery in DIRECT_READ mode
Key: BEAM-8275
URL: https://issues.apache.org/jira/browse/BEAM-8275
Project: Beam
Issue Type: New Feature
Components: dsl-sql
Reporter: Andrew Pilloud
Assignee: Kirill Kozlov
SQL currently only supports reading from BigQuery in DEFAULT (EXPORT) mode. We
also need to support DIRECT_READ mode. The method should be configurable by
TBLPROPERTIES through the SQL CLI. This will enable us to take advantage of the
DIRECT_READ features for filter and project push down.
