Doom Patrol

Geospatial data store based on Astra and Stargate leveraging both the keyspace and document APIs.

Components

Astra & Stargate

Awesome C*aaS and API interfaces for powering the data layer behind our application.

Setup

1. Create an Astra Database

2. Take note of the Database ID, Region, Username and Password

3. Export these values for the backend to use later

   export ASTRA_DATABASE_ID=00000000-0000-0000-0000-000000000000
   export ASTRA_REGION=us-east1
   
   export ASTRA_DATABASE_USERNAME=MyAwesomeUsername
   export ASTRA_DATABASE_PASSWORD=MrNobody
   export ASTRA_KEYSPACE=dooooom

4. Create a new table in the CQLSH Console

   CREATE TABLE dooooom.geohash (
       hash text PRIMARY KEY,
       id text
   );

Backend

Lightweight Flask application with helper libraries around GeoJSON, GeoHashing, and the Astra REST APIs.
