• Instructions

Application creates database named 'feedme' & collection named 'fixtures'

Before running a Test or the main Application, Start MongoDB from a linux terminal: sudo service mongod start

Start the feeme Service, from the project root directory: docker-compose up

After running a Test or the main Application, you can view the documents persisted in the fixtures collection of the 'feedme' database: use feedme db.fixtures.find().pretty()

• Further Comments

ZeroMq was used to implement the messgae queues for the advanced json packet sharding / partitioning. In the main Application, an executor service is used to 'simulate' the effect of runnning a single json publisher app and multiple independant NoSQL writers (json consumers) apps.
