Polling interval in file adapter.

Hi,

I have a doubt regarding the file adapter polling interval.

Suppose we get a file of size 512 MB and PI file adapter taking long time (say 15 Min) to process it, we have a polling interval of 10 min.

I have a 2 doubt in this case.

1. what will happen in the next polling interval. because the older file still is in process and it is still in the source folder location.

2. if at the same time there is new file get places in same folder location. then how the file adapter behave in this case. Is it start picking the second file or again poll the incomplete file.

I want to know that is PI maintaining some lock while processing some file from source folder.

regards,
