About
omniload is a polyglot data loader framework based on dlt, the open-source Python library for building data pipelines. dlt does the heavy lifting (schema inference, normalization, and incremental load state); omniload wraps it behind a single CLI and a URI scheme, so you can copy data between any source and any destination without writing pipeline code, either from your shell or the Python API.
omniload provides the same efficient incremental data loading modes
inherited by dlt: append, merge, and delete+insert.
Install
Container
For running omniload in a container environment, use the provided OCI
images.
docker run --rm ghcr.io/panodata/omniload:latest version
Package
For running or installing the omniload Python package,
we are recommending to use uv. 12
uvx omniload
Alternatively, if you like to install it account-wide on your system:
uv tool install omniload
Synopsis
CLI
Instruct omniload to read from the PostgreSQL table public.some_data,
and write to the BigQuery warehouse table omniload.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'
Python API
Using omniload.run_ingest, you can run the same
ingestion from your own application. The keyword arguments map one-to-one to the
CLI options, and it returns the dlt LoadInfo for the run (or None for a dry run).
from omniload import run_ingest
info = run_ingest(
source_uri="sqlite:///./source.db",
dest_uri="duckdb:///./warehouse.duckdb",
source_table="main.some_table",
dest_table="public.some_table",
)
print(info)
See the Python API documentation for dry runs, error handling, and passing enum options as strings.
