Methods in play

/get-visits

Get the list of all the Visit IDs present in the database. Used in populating the options of <select> component.
/get-articles

Get the list of all the Article IDs present in the database. Used in populating the options of <select> component.
/modify-behaviour?isJob=<?> or /modify-behaviour?visit_id=<?>&article_id=<?>

Simulate the user activity of opening another article.
- If isJob is set to one, then a bulk of users' activity is modified
- Else user with visit ID as visit_id have their article ID set as article_id
/fetch-trending?visit_id=<?>&article_id=<?>

Our main act. Based on article_id's category and user's geolocation, get the list of trending articles, sorted in decreasing viewership. Factors considered for "trendiness":
- Get latest user activity of past 2 minutes
- Filter out those articles whose publishing date is greater than 5 days
- Filter out those articles whose category doesn't match our current article's category *
- Filter out those users whose region doesn't match our current user's region *

Q: I have selected both article and visit ID and hit on submit, yet there has been no rendering for 5 seconds?

A: As I have not scheduled a job for mimicking user traffic, you might have to call /modify-behaviour?isJob=1 to get the populating stuff sorted.
