Feature #11984
closedtransfer frames in batch of sessions
0%
Description
This feature is used in case when frames are accumulated on the camera host due to either network or permanent storage used for the detination is not available.
A few things can be made more efficient if we don't have to consider new files streaming in.
The live-streaming version need to do inefficient text search. It is much faster to match in python set.interception the frames name of the session query results that specify the camera host and image data.
This new feature also first move all frame files into a tmp directory on the source, and then do rsync or mv of the whole directory. rsync is faster with directory.
