After doing some testing I realize that Backendless will prove to be extremely expensive.
Here is a simple example.
1 Android user requests 1 page of ITEMS, size = 10 (thats 1 call)
For each item you will need (isFavorite, likes, dislikes, comment-count, maybe an image), thats 5 queries per item
Now we are at 50 + 1 = 51 query for just flat opening app cost.
God forbid if he scrolls to the next page, thats another hit for 51 calls in the same minute.
Just to be VERY VERY VERY conservative, lets say one user costs you 51 + 51/2 ~= 77 calls/minute
Lets say you have the 1200 calls per minute account, you can afford only 1200/77 ~= 16 concurrent users.
And this is a low ball figure for 100$ / month.
If I am making a mistake in understanding API calls here, please correct me.
Even if my math is half correct, its really NOT FEASIBLE.
