Push Pi points and AF hierarchy

I would like to write an implementation to push pi points and AF structure on top of SDK. I understand there are different ways to achieve it - using data pipes or SDK.

Is there any way to push using PI Web API.


I would like to write an implementation to push AF structure and PI Data points using data pipes (preferably Web APIs). I have few queries:

1. Does data pipe only push latest data or out or order data also? My use case is to retrieve data points exist between certain time ranges (say 01/01/2016 - 01/31/2016) and any data point changed (or updated) between this range.

2. Suppose my Web API client is not up for some time then I need to put some buffer on top of data pipe so that when client will come alive it can pump missed data? Is there any watermarking (start pumping data after certain time) feature available? How buffering is handled?

3. Is there any way to achieve run time subscription to monitored attributes?
