API Wrapper For FMTM Splitter Microservice

[spwoodcock]

Is your feature request related to a problem? Please describe.

• Follow on from Modularisation of FMTM Splitter #62
• Once modularlised, we should consider an approach of having this as a microservice, with a very light http wrapper.
• Having a Python module is all well and good, but this relies on a database: ideally the user has a option to deploy with an existing db or a bundled db with the microservice.
• If a user could simply deploy this with a few commands, then pass in geojson files for splitting, it would be a much more user friendly tool and could potentially be adopted by others.

Describe the solution you'd like

Many options:

• Small FastAPI service to wrap the Python module here. Note we need to maintain /update this though...
• Something more lightweight possibly? We simply need a HTTP request to send a JSON payload, trigger SQL, return a JSON payload.

Additional context

• We can probably keep this as a Python package published on pypi too.
• That will allow flexibility for how the user decides to deploy (bundled in their own app, or standalone microservice).
