datatailr 0.1.112

Ready-to-Use Platform That Drives Business Insights

---

Datatailr empowers your team to streamline analytics and data workflows from idea to production without infrastructure hurdles.

What is Datatailr?

Datatailr is a platform that simplifies the process of building and deploying data applications.

It makes it easier to run and maintain large-scale data processing and analytics workloads.

What is this package?

This is the Python package for Datatailr, which allows you to interact with the Datatailr platform.

It provides the tools to build, deploy, and manage batch jobs, data pipelines, services and analytics applications.

Datatailr manages the underlying infrastructure so your applications can be deployed in an easy, secure and scalable way.

Installation

Installing the Python package

You can install the Datatailr Python package using pip:

pip install datatailr

Testing the installation

import datatailr

print(datatailr.__version__)
print(datatailr.__provider__)

Remote CLI (optional)

If you install the package outside the Datatailr platform, you can enable the remote dt CLI:

datatailr setup-cli

After datatailr login, you can print the OIDC cookie line for scripts or HTTP clients:

datatailr export-auth
eval "$(datatailr export-auth --shell)"   # sets DATATAILR_OIDC_HEADER

From Python (after datatailr login), read the same session at runtime:

from datatailr import (
    get_remote_http_headers,
    get_remote_oidc_cookie_line,
    get_remote_oidc_jwt,
    load_remote_client_config,
)

cfg = load_remote_client_config()
print(cfg.base_url)

token = get_remote_oidc_jwt()
line = get_remote_oidc_cookie_line()  # X-Datatailr-Oidc-Data=<jwt>

import requests
requests.get(f"{cfg.base_url}/api/user/ls", headers=get_remote_http_headers())

Example usage:

dt job ls
dt user ls
dt job save path/to/local/file.json

Notes:

• Remote CLI configuration inside a virtual environment only applies inside that environment.
• The remote CLI cannot be installed inside Datatailr containers; the native CLI is used there.

AI Agent Skills

The package includes agent skills that teach AI coding assistants (Cursor, Claude Code, Codex, Copilot, etc.) how to work with the Datatailr platform. Inside Datatailr workstations, skills are available automatically. On your local machine, run:

datatailr setup-skills

Quickstart

The following example shows how to create a simple data pipeline using the Datatailr Python package.

from datatailr import workflow, task

@task()
def func_no_args() -> str:
    return "no_args"


@task()
def func_with_args(a: int, b: float) -> str:
    return f"args: {a}, {b}"

@workflow(name="MY test DAG")
def my_workflow():
    for n in range(2):
        res1 = func_no_args().alias(f"func_{n}")
        res2 = func_with_args(1, res1).alias(f"func_with_args_{n}")
my_workflow(local_run=True)

Running this code will create a graph of jobs and execute it. Each node on the graph represents a job, which in turn is a call to a function decorated with @task().

Since this is a local run then the execution of each node will happen sequentially in the same process.

To take advantage of the datatailr platform and execute the graph at scale, you can run it using the job scheduler as presented in the next section.

Execution at Scale

To execute the graph at scale, you can use the Datatailr job scheduler. This allows you to run your jobs in parallel, taking advantage of the underlying infrastructure.

You will first need to separate your function definitions from the DAG definition. This means you should define your functions as a separate module, which can be imported into the DAG definition.

# my_module.py

from datatailr import task

@task()
def func_no_args() -> str:
    return "no_args"


@task()
def func_with_args(a: int, b: float) -> str:
    return f"args: {a}, {b}"

To use these functions in a batch job, you just need to import them and run in a DAG context:

from my_module import func_no_args, func_with_args
from datatailr import workflow

@workflow(name="MY test DAG")
def my_workflow():
    for n in range(2):
        res1 = func_no_args().alias(f"func_{n}")
        res2 = func_with_args(1, res1).alias(f"func_with_args_{n}")

schedule = Schedule(at_hours=0)
my_workflow(schedule=schedule)

This will submit the entire workflow for execution, and the scheduler will take care of running the jobs in parallel and managing the resources. The workflow in the example above will be scheduled to run daily at 00:00.
