Simple decorator for multiprocessing and psql insertion

Project description


PyPI version

gerardo provides decorators to easily compute in parallel and store the results in a PostgreSQL database.


See examples/ for more details.

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.
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)]


pip install gerardo --user
