tiozin 1.1.0

Tiozin, your friendly ETL framework

Tiozin

---

ETL shouldn't require 80 files, 50 YAMLs, and a PhD in complexity.

Tiozin brings it back to basics: Transform. Input. Output. Nothing more, nothing less.

A lightweight Python framework that makes data jobs declarative, testable, and actually enjoyable to write.

Quick Start

pip install tiozin

Option 1: Define a job in YAML

kind: Job
name: kinglear_word_count_job

org: tiozin
region: latam
domain: literature
product: shakespeare
model: kinglear
layer: refined

runner:
  kind: SparkRunner

inputs:
  - kind: SparkFileInput
    name: load_poems
    path: s3://{{org}}-{{domain}}-raw/{{product}}/{{model}}/date={{ DAY[-1] }}

transforms:
  - kind: SparkWordCountTransform
    name: word_count

outputs:
  - kind: SparkFileOutput
    name: save_word_counts
    path: s3://{{org}}-{{domain}}-{{layer}}/{{product}}/{{model}}/date={{ today }}

Run it:

tiozin run examples/jobs/shakespeare/kinglear_word_count_job.yaml

Option 2: Use Python directly

from tiozin import TiozinApp

app = TiozinApp()
app.run("examples/jobs/shakespeare/kinglear_word_count_job.yaml")

Done. No ceremony, no boilerplate.

Philosophy

Your uncle's advice: Keep it simple, readable, and testable.

• Declarative – Define what, not how
• Pluggable – Swap runners, registries, plugins as needed
• Metadata – Built-in metadata integration
• Observable – Logs that help
• Testable – Mock anything, validate everything

No magic. No surprises. Just clean data pipelines.
