Beneath is a serverless real-time data platform. Our goal is to create one end-to-end platform for data workers that combines data storage, processing, and visualization with data quality management and governance.
Beneath is a work in progress and your input makes a big difference! If you like it, star the project to show your support or reach out and tell us what you think.
The holy grail of data work is putting data science into production. It's glorious to build live dashboards that aggregate multiple data sources, send real-time alerts based on a machine learning model, or offer customer-specific analytics in your frontend.
But building a modern data management stack is a full-time job, and a lot can go wrong. If you were starting a project from scratch today, you might set up Postgres, BigQuery, Kafka, Airflow, DBT and Metabase just to cover the basics. Later, you would need more tools to do data quality management, data cataloging, data versioning, data lineage, permissions management, change data capture, stream processing, and so on.
Beneath is a new way of building data apps. It takes an end-to-end approach that combines data storage, processing, and visualization with data quality management and governance in one serverless platform. The idea is to provide one opinionated layer of abstraction, i.e. one SDK and UI, which under the hood builds on modern data technologies.
Beneath is inspired by services like Netlify and Vercel that make it remarkable easy for developers to build and run web apps. In that same spirit, we want to give data scientists and engineers the fastest developer experience for building data products.
We started with the data storage and governance layers. You can use the Beneath Beta today to store, explore, query, stream, monitor and share data. It offers several interfaces, including a Python client, a CLI, websockets, and a web UI. The beta is stable for non-critical use cases. If you try out the beta and have any feedback to share, we'd love to hear it!
Next up, we're tackling the data processing and data visualization layers, which will bring expanded opportunity for data governance and data quality management (see the roadmap at the end of this README for progress).
The snippet below presents a whirlwind tour of the Python API:
# Create a new table
table = await client.create_table("examples/demo/foo", schema="""
type Foo @schema {
foo: String! @key
bar: Timestamp
}
""")
# Write batch or real-time data
await table.write(data)
# Load into a dataframe
df = await beneath.load_full(table)
# Replay and subscribe to changes
await beneath.consume(table, callback, subscription_path="...")
# Analyze with SQL
data = await beneath.query_warehouse(f"SELECT count(*) FROM `{table}`")
# Lookup by key, range or prefix
data = await table.query_index(filter={"foo": {"_prefix": "bar"}})The image below shows a screenshot from the Beneath console. Check out the home page for a demo video.
The best way to try Beneath is with a free beta account. Sign up here. When you have created an account, you can:
- Install and authenticate the Beneath SDK
- Browse public projects and integrate using Python, JavaScript, Websockets and more
- Create a private or public project and start writing data
We're working on bundling a self-hosted version that you can run locally. If you're interested in self-hosting, let us know!
