[jira] [Created] (AIRFLOW-1892) Added capability in BigQuery hook
to extract data for selected columns
Kaxil Naik created AIRFLOW-1892:
-----------------------------------
Summary: Added capability in BigQuery hook to extract data for selected columns
Key: AIRFLOW-1892
URL: https://issues.apache.org/jira/browse/AIRFLOW-1892
Project: Apache Airflow
Issue Type: Improvement
Components: contrib, gcp
Affects Versions: 1.10.0
Reporter: Kaxil Naik
Assignee: Kaxil Naik
Priority: Minor
Fix For: 1.10.0
The `get_tabledata` method in `bigquery_hook` currently does not support extracting data for a specific field, instead, it extracts the full table.
The proposal is to add the parameter to extract data for specific columns from a BigQuery table. The idea after that is to create an operator to get data in a python list.
