Focus on What Matters

We've built mabel to enable Data Analysts to write complex data engineering tasks quickly and easily, so they could get on with doing what they do best.

from mabel import Reader

data = Reader(dataset="test_data")
print(data.count())

Key Features

• On-the-fly compression
• Low-memory requirements, even with terabytes of data
• Indexing and partitioning of data for fast reads
• Cursors for tracking reading position between processes
• Partial SQL DQL (Data Query Language) support
• Schema and data_expectations validation

Installation

From PyPI (recommended)

pip install --upgrade mabel

From GitHub

pip install --upgrade git+https://github.com/mabel-dev/mabel

A preview release of mabel is available from PyPI

pip install --upgrade mabelbeta

You may need to manually uninstall mabel before the test version will install.

These versions are usually labelled with an a (signifying alpha status) in the library version. Alpha versions are more likely to have functional issues.
