I have a couple of doubts about Feeds (custom ones):
1st: How can I make that the feed work only for a specific device(s) type(s). For example: I want to use as a callback key user.dst meta to populate 3 more metas, but as this user info is valid only for a specific aplication, I would like that only matchs the user.dst for that specific device type.
2nd: The csv or text file that upload, How bigger can be? Right now, I Have my csv file for my initial upload, and It have 1.13GB (more than 14 millions of lines). Do you think that the system can handle it?
thanks in advance.
