Re: Invoking methods from multiple threads - connection policy

["Frank Rehberger" <Frank Rehberger web de>]

Toralf,

if I remember correctly, there are at least these two options:
ORBIT_THREAD_HINT_PER_REQUEST
ORBIT_THREAD_HINT_PER_CONNECTION

I would recommend the second one (per-connection), if it comes to  
near-real-time processing, to avoid priority inversion.
