Introduction

Use endurance_etl to execute some simple ETL pipelines:

# json #

from endurance_etl import Tars

CONFIG = "sample.json"
# content =>
{
    "sources": [
        {
            "name": "csv_file_source",
            "path": "csv_file_source.csv",
            # ...other_kwargs
        }
    ],
    "targets": [
        {
            "name": "csv_file_target",
            "source": "source/csv_file_source",
            "target": "csv_file_target.csv",
            "transformations": [
                {
                    "function": "lambda df: df + 1"
                }
            ]
            # ...other_kwargs
        }
    ]
}
tars = Tars.from_json(CONFIG)
tars.do()

# yaml #

from endurance_etl import Tars

CONFIG = "sample.yaml"
# content =>
sources:
    csv_file_source:
        path: "csv_file_source.csv"
        # ...other_kwargs

targets:
    memory_target:
        source: "source/csv_file_source"
        target:
    csv_file_target:
        source: "source/csv_file_source"
        target: "csv_file_target.csv"
    excel_file_target:
        source: "target/memory_target"
        target: "excel_file_target.xlsx"

tars = Tars.from_yaml(CONFIG)
tars.do()
