Goals and Design

Replace DynamoDB

• Meadowlark - MongoDB
• Meadowlark - PostgreSQL
• Meadowlark - Durable Change Data Capture

Provide a full-access mode for authorization

• Meadowlark 0.2.0 - Security

Architecture

1. Runs on localhost!
2. New features / functionality:
   1. MongoDB transactional storage
   2. PostgreSQL transactional storage
   3. Node.js front end
   4. Data out from MongoDB to Kafka 
3. Removing DynamoDB - see Meadowlark - Referential Integrity in Document Databases for more information.
4. Temporarily, AWS support is broken: we have not orchestrated a replacement for DynamoDB.

Demonstration

Be sure to edit the .env  file as mentioned near the end of the following script:

# Get code
> git clone https://github.com/Ed-Fi-Exchange-OSS/Meadowlark
> git checkout 0.2.0
> cd Meadowlark
> yarn install & yarn build

# Startup backend services
> .eng/docker.ps1

# Run locally
> pushd Meadowlark-js/services/meadowlark-fastify
> cp .env.example .env    # And edit it appropriately
> yarn start:local

# See test/http/local* for various requests to run in Visual Studio Code
