is it possible to define Stream in term of Pojo class definitions as in ESPER?

Answer 1

In siddhi you cannot define streams in term of Pojo class definitions. Siddhi only supports tuples and hence you have to define the stream as follows;

E.g.

define PersonStream (name string, address_streat string, address_city string );
