About

An abstraction of connections to real data sources for extraction applications usage.

It implements simple methods for extraction preparation, monitoring, execution and cleaning into a class, meant to be inherited.

The goal of this project consists in creating a standardized API for communicating with data sources in applications written in Python.

You can simply install it using pip as follows:

$ pip install sour-cereal

Usage

from sour_cereal import SourceConnection

class FooDataSource(SourceConnection):
    def get_status_of_extraction(self: 'FooDataSource', *args, **kwargs):
        return datetime.now()

    def check_availability_of_extraction(self: 'FooDataSource', status: datetime):
        return status.hour >= 7		# data is ready only after 7pm

    def execute_extraction(self: 'FooDataSource', *args, **kwargs):
		# Extract some data
