Sglossu / redis_pubsub_queue

Test environment of using Redis pubsub as a queue broker.

Producer generates JSON messages and puts them as a payload into a Redis pubsub queue. Consumer receives an argument with a list of account numbers like this:

{
   "metadata": {
       "from": 1023461745,
       "to": 5738456434
   },
   "amount": 10000
}

and puts them as a payload into a Redis pubsub queue.

Consumer receives an argument with a list of account numbers like this:

~$ python consumer.py -e 7134456234,3476371234

where -e is a parameter receiving a list of bad guys' account numbers. When started, it reads messages from a pubsub queue and print them to stdout on one line each. For accounts from the "bad guys' list" if they are specified as a receiver consumer switches sender and receiver for the transaction. But this happends only in case "amount" is not negative.

For example, if producer generates three messages like these:

{"metadata": {"from": 1111111111,"to": 2222222222},"amount": 10000}
{"metadata": {"from": 3333333333,"to": 4444444444},"amount": -3000}
{"metadata": {"from": 2222222222,"to": 5555555555},"amount": 5000}

consumer started like ~$ python consumer.py -e 2222222222,4444444444 should print out:

{"metadata": {"from": 2222222222,"to": 1111111111},"amount": 10000}
{"metadata": {"from": 3333333333,"to": 4444444444},"amount": -3000}
{"metadata": {"from": 2222222222,"to": 5555555555},"amount": 5000}
