Hi,
I would be interested in "logging" some data, like how long did a player stay online, which items he bought, what "units selection" he used for a battle, etc.
So, not intensive logging but only the essential stuff, probably around a line per player per few minutes or so. The aim is to make statistics and analyze where are the critical points where the player leaves, which units are too weak or too strong, what items are liked/disliked...
I was thinking of using bigDB directly but since the max size of an object would be 500k, that would be quickly reached if the amount of users increase. Ideally, you should also connect to a "logging" room, etc. ...it's not very practical.
The other alternative is to write to a remote server that writes a rolling file. However, since you want to provide a full stack and have already the infrastructure there, I guess it should ideally be placed on your side.
This is just a suggestion, thanks for reading.
