[![PyPI version](https://badge.fury.io/py/gerardo.svg)](https://badge.fury.io/py/gerardo)

**gerardo** provides decorators to easily compute in parallel and store the

results in a PostgreSQL database.

## Usage

See `examples/example.py` for more details.

```python

from gerardo import psql_mp_insert, psql_handler

# Set a PostgreSQL handler

pghost = os.environ["PGHOST"]

DSN = {

    "host": pghost,

    "port": "",

    "user": "",

    "password": "",

    "dbname": "example_db",

}

PSQL_TABLE = "test_table"

COLUMNS = [('x', 'INT'), ('y', 'INT')]

PH = psql_handler(DSN, PSQL_TABLE, COLUMNS)

# Define a single-variable function.

@psql_mp_insert(PH)

def f(x):

    return (x[0]+x[1], x[0]*x[1])

# Compute by forming a list of arguments

list_args = [(x, y) for x in range(5) for y in range(10)]

f(list_args)

```

## Installation
