# atlasclient — Apache Atlas client

License: permissive · Maintenance: active · Downloads: 1.8M/mo

## What it is and what it does

atlasclient is a Python wrapper around Apache Atlas's REST API v2 that abstracts the complexity of direct HTTP calls to metadata operations. It provides object-oriented access to Atlas entities, classifications, and search functionality, with lazy loading so requests are only made when data is actually needed. The client transparently handles multi-step REST operations—for example, fetching classifications for an entity—so you don't need to know the underlying API structure.

The package is designed for developers integrating with Apache Atlas for data governance, metadata discovery, and lineage tracking. It has no external runtime dependencies, making installation straightforward, but it does require a live Atlas server to connect to. The codebase is marked Pre-Alpha and has not been updated since August 2019, so it may have compatibility gaps with newer Atlas versions or Python releases.

Use it for:

- Query and retrieve metadata entities from Apache Atlas by type, attribute, or search criteria without writing raw REST calls.
- Programmatically access entity classifications and relationships as Python objects with automatic sub-resource loading.
- Integrate Atlas metadata operations into Python data pipelines or governance automation scripts.
- Parse qualified names and perform basic searches on Atlas data assets during data discovery workflows.

## Worth the install?

AI-flagged interpretation of the facts above — verify before relying.

A Python client for Apache Atlas REST API v2 that provides lazy-loaded access to metadata entities, classifications, and search operations without requiring direct knowledge of underlying REST endpoints.

Yes, if you are working with Apache Atlas v2 and need a Python client to avoid raw HTTP calls. No, if you require active maintenance, modern Python version support beyond 3.6, or compatibility with recent Atlas releases—the package has not been updated since 2019 and carries Pre-Alpha status. The high install friction and lack of runtime dependencies are not blockers, but the stale release history is a real concern for long-term use.

## Install

pip install atlasclient
uv add atlasclient
poetry add atlasclient

## Installing atlasclient

Before you install: High install friction and no runtime dependencies. The package is marked Pre-Alpha in development status and has not been updated since 2019-08-19, despite the repository showing recent activity. Maintenance status is marked active, but the gap between the latest release and current date suggests the package may not receive timely updates for compatibility issues.

License in practice: Licensed under Apache Software License 2.0, a permissive open-source license. You can use, modify, and distribute the package freely, including in commercial projects, provided you include a copy of the license and state significant changes.

Quickstart:

from atlasclient.client import Atlas
client = Atlas('atlas.host', port=21000, username='admin', password='admin')
params = {'typeName': 'DataSet', 'attrName': 'name', 'attrValue': 'data'}
results = client.search_attribute(**params)

Requires a running Apache Atlas server with REST API v2 endpoint accessible at the specified host and port; authentication credentials must be valid.

Verify before relying:

- Whether the package works with modern Python versions beyond 3.6, given classifiers list only up to 3.6 and no requires_python constraint is specified.
- Current compatibility with recent Apache Atlas versions, given the last release was 2019-08-19.
- Whether multiprocessing support mentioned as a TODO feature has been implemented.
