Hash Processor App [coding challenge]

The task is to implement two applications that generate and process data using RabbitMQ.

Application 1 [API]

• REST API application.
• Endpoint POST /hashes generates 40.000 random SHA1 hashes and sends them to RabbitMQ queue for further processing.
• Endpoint GET /hashes returns the number of hashes from the database grouped by day in JSON.

Application 2 [Processor]

• Background worker application.
• Connects to RabbitMQ queue and processes messages in parallel using 4 threads.
• Saves messages into the database table hashes (id, date, sha1).

Extra features

• Split generated hashes into batches and send them into RabbitMQ in parallel.
• Retrieve hashes from the database without recalculating data on the fly.
