Copy data between any source and any destination.

About

omniload is a polyglot data loader framework based on dlt. It allows you to load data from any source into any destination, either using a concise CLI from your shell, or the Python API from your own applications.

omniload provides the same efficient incremental data loading modes inherited by dlt: append, merge, and delete+insert.

Install

We recommend using uv to install or run omniload.

pip install uv
uvx omniload

Alternatively, if you'd like to install it globally:

uv pip install --system omniload

While installation with vanilla pip is possible, it's an order of magnitude slower.

Synopsis

The next command instructs omniload to read the table public.some_data from your PostgreSQL instance, and to write the data to your BigQuery warehouse under the schema omniload and table some_data.

omniload ingest \
    --source-uri 'postgresql://admin:admin@localhost:8837/web?sslmode=disable' \
    --source-table 'public.some_data' \
    --dest-uri 'bigquery://<your-project-name>?credentials_path=/path/to/service/account.json' \
    --dest-table 'omniload.some_data'
