Pachyderm: Data Versioning, Data Pipelines, and Data Lineage
Pachyderm is a tool for production data pipelines. If you need to chain together data scraping, ingestion, cleaning, munging, wrangling, processing, modeling, and analysis in a sane way, then Pachyderm is for you. If you have an existing set of scripts which do this in an ad-hoc fashion and you're looking for a way to "productionize" them, Pachyderm can make this easy for you.
Features
- Containerized: Pachyderm is built on Docker and Kubernetes. Whatever languages or libraries your pipeline needs, they can run on Pachyderm which can easily be deployed on any cloud provider or on prem.
- Version Control: Pachyderm version controls your data as it's processed. You can always ask the system how data has changed, see a diff, and, if something doesn't look right, revert.
- Provenance (aka data lineage): Pachyderm tracks where data comes from. Pachyderm keeps track of all the code and data that created a result.
- Parallelization: Pachyderm can efficiently schedule massively parallel workloads.
- Incremental Processing: Pachyderm understands how your data has changed and is smart enough to only process the new data.
Getting Started
Install Pachyderm locally or deploy on AWS/GCE/Azure in about 5 minutes.
