Say for instance I have a list of document objects that I am displaying and each time I click on that document, I want to save a timestamp to the database, in an field called 'clicked'.
{
id: 1,
clicked: ['timestamp1', 'timestamp2']
}
Should this field be an array of timestamps? It just seems like it would require a lot of effort to push an entire array every time just one timestamp is added. Would it make more sense to just make the clicked value a whole new collection or is there some other structure I'm overlooking?
