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. --Srinath On Thu, Jul 25, 2013 at 4:30 PM, Anjana Fernando <[email protected]> wrote: > Hi, > > In the search, the part where we give the conditions, this approach > doesn't handle the ordering of the conditions, like (stream1.prop1="1" or > stream2.prop2="2") and (stream1.prop3="3") kind of a scenario.
