Session API

Session is the context to use computing, storage and federation resouraces. At most situation, users should not concern how Session is create. FATE-Flow is responsed to create and init Session when Task launched.

For those who want to use computing, storage and federation api outside FATE-Flow Task, flowing is a short guide.

1. init Session

   sess = Session()
   sess.as_global()
   
   # flowing is optional, call if needed
   
   # init computing
   sess.init_computing(...)
   
   # init federation
   sess.init_federation(...)
   
   # init federation
   sess.init_storage(...)

2. calling specific api

   computing = sess.computing
   federation = sess.federation
   storage = sess.storage

3. computing api has a shortcut

   from fate_arch.session import computing_session
   computing_session.init(...)
   computing_session.parallelize(...)
