# AGE AGType parser and driver support for Python
AGType parser and driver support for [Apache AGE](https://age.apache.org/), graph extension for PostgreSQL.

### Features
* Unmarshal AGE result data(AGType) to Vertex, Edge, Path
* Cypher query support for Psycopg2 PostgreSQL driver (enables to use cypher queries directly)

### Prerequisites
* over Python 3.9
* This module runs on [psycopg2](https://www.psycopg.org/) and [antlr4-python3](https://pypi.org/project/antlr4-python3-runtime/)
```
sudo apt-get update
sudo apt-get install python3-dev libpq-dev
git clone https://github.com/apache/age.git
cd age/drivers/python
```

### Install required packages
```
pip install -r requirements.txt
```

### Test
```
python test_age_py.py \
-host "127.0.0.1" \
-db "postgres" \
-u "postgres" \
-pass "agens" \
-port 5432 \
-gn "test_graph"
```

```
python -m unittest -v test_agtypes.py
```

### Build from source
```
python setup.py install
```

CREATE EXTENSION age;
LOAD 'age';
SET search_path = ag_catalog, "$user", public;
```

### Usage
* If you are familiar with Psycopg2 driver : Go to [Jupyter Notebook : Basic Sample](samples/apache-age-basic.ipynb) 
* Simpler way to access Apache AGE [AGE Sample](samples/apache-age-note.ipynb) in Samples.
* Agtype converting samples: [Agtype Sample](samples/apache-age-agtypes.ipynb) in Samples.
