Pachyderm: A Containerized, Version-Controlled Data Lake

Pachyderm is:

Getting Started

Install Pachyderm locally or deploy on AWS/GCE/Azure in about 5 minutes.

You can also refer to our complete developer docs to see tutorials, check out example projects, and learn about advanced features of Pachyderm.

What's new about Pachyderm? (How is it different from Hadoop?)

There are two bold new ideas in Pachyderm:

  • Containers as the core processing primitive
  • Version Control for data

These ideas lead directly to a system that's much more powerful, flexible and easy to use.

To process data, you simply create a containerized program which reads and writes to the local filesystem. You can use any tools you want because it's all just going in a container! Pachyderm will take your container and inject data into it. We'll then automatically replicate your container, showing each copy a different chunk of data. With this technique, Pachyderm can scale any code you write to process up to petabytes of data (Example: distributed grep).

Pachyderm also version controls all data using a commit-based distributed filesystem (PFS), similar to what git does with code. Version control for data has far reaching consequences in a distributed filesystem. You get the full history of your data, can track changes and diffs, collaborate with teammates, and if anything goes wrong you can revert the entire cluster with one click!

Version control is also very synergistic with our containerized processing engine. Pachyderm understands how your data changes and thus, as new data is ingested, can run your workload on the diff of the data rather than the whole thing. This means that there's no difference between a batched job and a streaming job, the same code will work for both!

Usage Metrics

Pachyderm automatically reports anonymized usage metrics. These metrics help us understand how people are using Pachyderm and make it better. They can be disabled by setting the env variable METRICS to false in the pachd container.

Functions

func Asset

func Asset(name string) ([]byte, error)

Asset loads and returns the asset for the given name. It returns an error if the asset could not be found or could not be loaded.

func AssetDir

func AssetDir(name string) ([]string, error)

AssetDir returns the file names below a certain directory embedded in the file by go-bindata. For example if you run go-bindata on data/... and data contains the following hierarchy:

data/
  foo.txt
  img/
    a.png
    b.png

then AssetDir("data") would return []string{"foo.txt", "img"} AssetDir("data/img") would return []string{"a.png", "b.png"} AssetDir("foo.txt") and AssetDir("notexist") would return an error AssetDir("") will return []string{"data"}.

func AssetInfo

func AssetInfo(name string) (os.FileInfo, error)

AssetInfo loads and returns the asset info for the given name. It returns an error if the asset could not be found or could not be loaded.

func AssetNames

func AssetNames() []string

AssetNames returns the names of the assets.

func MustAsset

func MustAsset(name string) []byte

MustAsset is like Asset but panics when Asset would return an error. It simplifies safe initialization of global variables.

func RestoreAsset

func RestoreAsset(dir, name string) error

RestoreAsset restores an asset under the given directory

func RestoreAssets

func RestoreAssets(dir, name string) error

RestoreAssets restores an asset under the given directory recursively
