We don't want to check out a connection from the connection pool until we know we have been granted a thread from the thread pool to execute on. If we grab the connection when the Upload object is created, and we have to wait 5 seconds to get a thread for runImpl() to execute on, we'll simply be tieing up that connection for the entire duration of the wait. So use a Provider instead so we can defer obtaining the connection. Change-Id: I9ac360981fb1ad3e09e77ad579e9203686b14494 Signed-off-by: Shawn O.
