Hi Anjana,

For example, stream1.prop1="1" -> stream2.prop1="1" to show the ordering
(note the arrow).

Actually, this is the CEP event pattern format (
http://wso2.com/library/articles/2013/06/understanding-siddhi-powers-wso2-cep-2x,
see sequence).
IMHO, if we need to show temporal ordering, CEP has the format. May be
there is room to improve, but in which case we fix both.

Sinthuja, the model we give to end users is EventStreams. IMHO, it is best
to let him search thinking event steam instead of row Cassandra.
