This is then stored in a table on Amazon DynamoDB, which is then queried by users. This set-up was used to test a possible set up for future live data pulling. One of the issues that might be faced is rate limits. If the project scales to the point where we have too many users constantly polling the endpoints, we might hit a limit. Thus, this method is tested to allow for relevant data to be cached, and users will then request the cached data rather than directly from the live data. Whether this is neccessary is yet to be determined.
