Sessions

Sessions are the key operation of FirstBatch. Each visitor to your app creates a session through FirstBatch SDK. 
Sessions are required for FirstBatch to operate.
There are two types of sessions
Temporary: Session is destroyed within 1 hour, Id created randomly by FirstBatch
session = personalized.session(
                algorithm=AlgorithmLabel.SIMPLE, 
                vdbid="my_db"
                )
Persistent: Session is persistent, id is given by the user 
session = personalized.session(
                session_id="newid",
                algorithm=AlgorithmLabel.SIMPLE, 
                vdbid="my_db"
                )
Stateless
FirstBatch manages sessions for you. An algorithm has multiple states and each session can be at a different state of the same algorithm or even a different algorithm. This design is to make it easy to integrate a stateless backend with FirstBatch and reduce development complexity.
Attributes
A session consists of:
ID -> session ID
Algorithm -> Type AlgorithmLabel
State -> State of the algorithm
User Embeddings -> List of vectors and their corresponding weights
Each type of Signal and Batch action updates the session state with the FirstBatch SDK.
