Extract Transform Load (ETL) from Code

The example below reads data from an http source (github) and will copy the data to a csv file and to a database. This example illustrates the one-to-many ETL features.

In [2]:
#
# Writing to Google Bigquery database
#
import transport
from transport import providers
import pandas as pd
import os

#
#
source = {"provider": "http", "url": "https://raw.githubusercontent.com/codeforamerica/ohana-api/master/data/sample-csv/addresses.csv"}
target =  [{"provider": "files", "path": "addresses.csv", "delimiter": ","}, {"provider": "sqlite", "database": "sample.db3", "table": "addresses"}]

_handler = transport.get.etl (source=source,target=target)
_data = _handler.read() #-- all etl begins with data being read
_data.head()
