Problem Statement: There's a queue which has N producers at one end and N consumers at the other end. The Producers get their input from an SDK. The queue actions can be controlled by APIs. Now When there are 1000+ orders placed in a minute in Myntra portal, come up with a solution in the framework on how you will validate the packets sent and received are the same in the Queue? Note: Here there are N producers and N consumers. Any consumer can receive a packet from any producer. There can also be scenarios that Queue is blocked and not flushed at for a very long time. Due to high traffic, the queue may not drain all the packets at the regular period of interval. Keep all the negative scenarios in mind while designing this framework.
