I have been trying to build a dynamic array logic to dynamically automate the calculation of days in inventory of some products. I am not an expert in using functions like scan/lambda and I have been running into issues related to the fact that a selling transaction might involve selling ite...

Amazon’s FIFO queues also have an exactly-once processing feature which deduplicates messages within a five-minute window. Note, however, that there are some caveats with this, the obvious one being duplicate delivery outside of the five-minute window. A mission-critical system would have to ...
AWS provides two queues inSQS serviceone is normal queue and the other one is FIFO queues. The normal queues ensures delivery but not in the order you inserted into it. While FIFO queues ensures the order in which you pushed the message into the queue. This is the reason these queues are...
