What is Ibis?

Ibis is the portable Python dataframe library:

See the documentation on "Why Ibis?" to learn more.

Getting started

You can pip install Ibis with a backend and example data:

pip install 'ibis-framework[duckdb,examples]'

๐Ÿ’ก Tip

See the installation guide for more installation options.

Then use Ibis:

>>> import ibis
>>> ibis.options.interactive = True
>>> t = ibis.examples.penguins.fetch()
>>> t

๐Ÿ’ก Tip

See the getting started tutorial for a full introduction to Ibis.

Python + SQL: better together

For most backends, Ibis works by compiling its dataframe expressions into SQL:

>>> ibis.to_sql(g)
SELECT
  "t1"."species",
  "t1"."island",
  "t1"."count"
FROM (
  SELECT
    "t0"."species",
    "t0"."island",
    COUNT(*) AS "count"
  FROM "penguins" AS "t0"
  GROUP BY
    1,
    2
) AS "t1"
ORDER BY
  "t1"."count" ASC

You can mix SQL and Python code:

>>> a = t.sql("SELECT species, island, count(*) AS count FROM penguins GROUP BY 1, 2")
>>> a

This allows you to combine the flexibility of Python with the scale and performance of modern SQL.

Backends

Ibis supports 20+ backends:

How it works

Most Python dataframes are tightly coupled to their execution engine. And many databases only support SQL, with no Python API. Ibis solves this problem by providing a common API for data manipulation in Python, and compiling that API into the backendโ€™s native language. This means you can learn a single API and use it across any supported backend (execution engine).

Ibis broadly supports two types of backend:

  1. SQL-generating backends
  2. DataFrame-generating backends

Ibis backend types

Portability

To use different backends, you can set the backend Ibis uses:

>>> ibis.set_backend("duckdb")
>>> ibis.set_backend("polars")
>>> ibis.set_backend("datafusion")

Typically, you'll create a connection object:

>>> con = ibis.duckdb.connect()
>>> con = ibis.polars.connect()
>>> con = ibis.datafusion.connect()

And work with tables in that backend:

>>> con.list_tables()
['penguins']
>>> t = con.table("penguins")

You can also read from common file formats like CSV or Apache Parquet:

>>> t = con.read_csv("penguins.csv")
>>> t = con.read_parquet("penguins.parquet")

This allows you to iterate locally and deploy remotely by changing a single line of code.

๐Ÿ’ก Tip

Check out the blog on backend agnostic arrays for one example using the same code across DuckDB and BigQuery.
