**Astro Python SDK** is a Python SDK for rapid development of extract, transform, and load workflows in [Apache Airflow](https://airflow.apache.org/). It allows you to express your workflows as a set of data dependencies without having to worry about ordering and tasks. The Astro Python SDK is maintained by [Astronomer](https://astronomer.io).
## Prerequisites
- Apache Airflow >= 2.1.0.
## Install
The Astro Python SDK is available at [PyPI](https://pypi.org/project/astro-sdk-python/). Use the standard Python
[installation tools](https://packaging.python.org/en/latest/tutorials/installing-packages/).
To install a cloud-agnostic version of the SDK, run:
```shell
pip install astro-sdk-python
```
You can also install dependencies for using the SDK with popular cloud providers:
```shell
pip install astro-sdk-python[amazon,google,snowflake,postgres]
```
## Quickstart
1. Ensure that your Airflow environment is set up correctly by running the following commands:
```shell
export AIRFLOW_HOME=`pwd`
export AIRFLOW__CORE__XCOM_BACKEND=astro.custom_backend.astro_custom_backend.AstroCustomXcomBackend
export AIRFLOW__ASTRO_SDK__STORE_DATA_LOCAL_DEV=true
airflow db init
```
> **Note:** `AIRFLOW__CORE__ENABLE_XCOM_PICKLING` no longer needs to be enabled for `astro-sdk-python`. This functionality is now deprecated as our custom xcom backend handles serialization.
The `AIRFLOW__ASTRO_SDK__STORE_DATA_LOCAL_DEV` should only be used for local development. The [XCom backend docs](https://astro-sdk-python.readthedocs.io/en/latest/guides/xcom_backend.html#airflow_xcom_backend) give further details about how to set this up in non-local environments.
Currently, custom XCom backends are limited to data types that are json serializable. Since Dataframes are not json serializable, we need to enable XCom pickling to store dataframes.
The data format used by pickle is Python-specific. This has the advantage that there are no restrictions imposed by external standards such as JSON or XDR (which can’t represent pointer sharing); however it means that non-Python programs may not be able to reconstruct pickled Python objects.
Read more: [enable_xcom_pickling](https://airflow.apache.org/docs/apache-airflow/stable/configurations-ref.html#enable-xcom-pickling) and [pickle](https://docs.python.org/3/library/pickle.html#comparison-with-json):
2. Create a SQLite database for the example to run with:
```shell
# The sqlite_default connection has different host for MAC vs. Linux
export SQL_TABLE_NAME=`airflow connections get sqlite_default -o yaml | grep host | awk '{print $2}'`
sqlite3 "$SQL_TABLE_NAME" "VACUUM;"
```
3. Copy the following workflow into a file named `calculate_popular_movies.py` and add it to the `dags` directory of your Airflow project:
https://github.com/astronomer/astro-sdk/blob/d5aa768b2d4bca72ef98f8d533fe3f99624b172f/example_dags/calculate_popular_movies.py#L1-L37
Alternatively, you can download `calculate_popular_movies.py`
```shell
curl -O https://raw.githubusercontent.com/astronomer/astro-sdk/main/python-sdk/example_dags/calculate_popular_movies.py
```
4. Run the example DAG:
```sh
airflow dags test calculate_popular_movies `date -Iseconds`
```
5. Check the result of your DAG by running:
```shell
sqlite3 "$SQL_TABLE_NAME" "select * from top_animation;" ".exit"
```
You should see the following output:
```shell
$ sqlite3 "$SQL_TABLE_NAME" "select * from top_animation;" ".exit"

## Available operations
The following are some key functions available in the SDK:
- [`load_file`](https://astro-sdk-python.readthedocs.io/en/stable/astro/sql/operators/load_file.html): Load a given file into a SQL table
- [`transform`](https://astro-sdk-python.readthedocs.io/en/stable/astro/sql/operators/transform.html): Applies a SQL select statement to a source table and saves the result to a destination table
- [`drop_table`](https://astro-sdk-python.readthedocs.io/en/stable/astro/sql/operators/drop_table.html): Drops a SQL table
- [`run_raw_sql`](https://astro-sdk-python.readthedocs.io/en/stable/astro/sql/operators/raw_sql.html): Run any SQL statement without handling its output
- [`append`](https://astro-sdk-python.readthedocs.io/en/stable/astro/sql/operators/append.html): Insert rows from the source SQL table into the destination SQL table, if there are no conflicts
- [`merge`](https://astro-sdk-python.readthedocs.io/en/stable/astro/sql/operators/merge.html): Insert rows from the source SQL table into the destination SQL table, depending on conflicts:
- `ignore`: Do not add rows that already exist
- `update`: Replace existing rows with new ones
- [`export_file`](https://astro-sdk-python.readthedocs.io/en/stable/astro/sql/operators/export.html): Export SQL table rows into a destination file
- [`dataframe`](https://astro-sdk-python.readthedocs.io/en/stable/astro/sql/operators/dataframe.html): Export given SQL table into in-memory Pandas data-frame
For a full list of available operators, see the [SDK reference documentation](https://astro-sdk-python.readthedocs.io/en/stable/operators.html).
## Documentation
The documentation is a work in progress--we aim to follow the [Diátaxis](https://diataxis.fr/) system:
