BigQuery Foreign Data Wrapper for PostgreSQL

Project Description

bigquery_fdw: BigQuery Foreign Data Wrapper for PostgreSQL
==========================================================

bigquery_fdw is a BigQuery foreign data wrapper for PostgreSQL using
`Multicorn <https://github.com/Kozea/Multicorn>`__.

It allows to write queries in PostgreSQL SQL syntax using a foreign
table. It supports most of BigQuery’s `data
types <docs/data_types.md>`__ and `operators <docs/operators.md>`__.

Features and limitations
------------------------

- Table partitioning is supported. `You can use partitions in your SQL
queries <docs/table_partitioning.md>`__.
- Queries are parameterized when sent to BigQuery
- BigQuery’s standard SQL support (legacy SQL is not supported)
- Authentication works with a “`Service
Account <docs/service_account.md>`__” Json private key

`Read more <docs/README.md>`__.

Requirements
------------

- PostgreSQL >= 9.5
- Python 3

Dependencies
------------

Dependencies required to install bigquery_fdw:
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

- ``postgresql-server-dev-X.Y``
- ``python3-pip``
- ``python3-dev``
- ``make``
- ``gcc``

Major dependencies installed automatically during the installation process:
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

- `Google Cloud
BigQuery <https://pypi.org/project/google-cloud-bigquery/>`__
- `Multicorn <https://github.com/Kozea/Multicorn>`__

Installation
------------

.. code:: bash

# Install `setuptools` if necessary
pip3 install --upgrade setuptools

# Install Multicorn
git clone git://github.com/Kozea/Multicorn.git && cd Multicorn
export PYTHON_OVERRIDE=python3
make && make install

# Install bigquery_fdw
pip3 install bigquery-fdw

Usage
-----

We recommend testing the `BigQuery client
connectivity <docs/test_client.md>`__ before trying to use the FDW.

With ``psql``:

.. code:: sql

CREATE EXTENSION multicorn;

CREATE SERVER bigquery_srv FOREIGN DATA WRAPPER multicorn
OPTIONS (
wrapper 'bigquery_fdw.fdw.ConstantForeignDataWrapper'
);

CREATE FOREIGN TABLE my_bigquery_table (
column1 text,
column2 bigint
) SERVER bigquery_srv
OPTIONS (
fdw_dataset 'my_dataset',
fdw_table 'my_table',
fdw_key '/opt/bigquery_fdw/user.json'
);

Options
