>             Project: Samza
>          Issue Type: Sub-task

> The task is to implement a join operator for the query below:
> {code}
> SELECT STREAM a.time as time, a.id as id, a.a, b.b FROM A as a JOIN B as b ON 
>  a.id = b.id AND a.time > b.time - 3 MIN AND a.time < b.time + 5 MIN
> {code}
> The join operator needs to implement the following two functions:
> # Given a incoming message from window operator from stream A, retrieve all 
> relevant messages for the join from stream B's window operator
> # Given two sets of messages from stream A and B, perform the join logic to 
> create the output tuples.
