bookstore 2.2.0

Storage Workflows for Notebooks

bookstore :books:

bookstore :books: provides tooling and workflow recommendations for storing :cd: , scheduling :calendar:, and publishing :book: notebooks.

Note: Supports installation on Python 3.6 and above. Processes notebooks from Python 2 or Python 3.

Automatic Notebook Versioning

Every save of a notebook creates an immutable copy of the notebook on object storage.

To simplify implementation, we currently rely on S3 as the object store, using versioned buckets.

Storage Paths

All notebooks are archived to a single versioned S3 bucket with specific prefixes denoting the lifecycle of the notebook:

• /workspace - where users edit
• /published - public notebooks (to an organization)

Each notebook path is a namespace that an external service ties into the schedule. We archive off versions, keeping the path intact (until a user changes them).

Prefix	Intent
/workspace/kylek/notebooks/mine.ipynb	Notebook in “draft”
/published/kylek/notebooks/mine.ipynb	Current published copy

Scheduled notebooks will also be referred to by the notebook key. In addition, we'll need to be able to surface version IDs as well.

Transitioning to this Storage Plan

Since most people are on a regular filesystem, we'll start with writing to the /workspace prefix as Archival Storage (writing on save using a post_save_hook for a Jupyter contents manager).

---

Publishing

The bookstore publishing endpoint is a serverextension to the classic Jupyter server.

This means if you are developing this you will need to explicitly enable it to use the endpoint.

To do so you run: jupyter serverextension enable --py bookstore.

If you wish to enable it only for your current environment, run: jupyter serverextension enable --py bookstore --sys-prefix.

Installation

bookstore requires Python 3.6 or higher.

1. Clone this repo.
2. At the repo's root, enter in the Terminal: python3 -m pip install . (Tip: don't forget the dot at the end of the command)

Configuration

# jupyter config
# At ~/.jupyter/jupyter_notebook_config.py for user installs on macOS
# See https://jupyter.readthedocs.io/en/latest/projects/jupyter-directories.html for other places to plop this
