Demo the ServiceX DID Library

Usage

This is a demo DID finder for the ServiceX project. It can be run in ServiceX and if given an appropriate dataset name, it will return a fixed set of data files to the system.

It is meant to demo usage of the ServiceX_DID library, and be used as a template to build new ServiceX DID finders. You'll need to add a deployment.yaml to the ServiceX chart in order to get this to work. Please see other did_finder deployment.yaml files and pattern it off this one.

Testing Demo in ServiceX

To test this in ServiceX perform the following steps:

1. Start a servicex instance with the demo did finder running
2. Launch the sample.simple_query.ipynb in a notebook server. If you install all development packages in the toml file, you'll have everything you need.
3. Run the sample. On a home internet, the sample takes about 20 seconds to complete.

Creating a new ServiceX DID Finder

To see how this is created see the following files in this repository:

• src/demo.did.py - Contains the code that returns a single file if the proper dataset name is queried.
• Dockerfile - Builds the container that can run in the ServiceX environment.
• requirements.txt - Contains all the packages required to run the did finder.

This repository is a template repository - which makes it very easy to start as a template.
