Hi,
Can we do the $subject ?
Because I have a requirement for inserting the output of an EPL statement to
another event stream within a query and using that event stream in another
query. Therefore in that case, I don't need to have output topic in my first
query. But in CEP bucket, it is a mandatory field. So can we make that
optional?
The following format is what I required.
<query name="query1">
<expression type="inline" listenerName="queryListener1">
insert into stream2 select a,b,c,...,f from stream1 .....
</expression>
</query>
<query name="query2">
<expression type="inline" listenerName="queryListener2">
select a,b,c,..,e from stream2 where a > 3 and ....
</expression>
<output topic="outputTopic" brokerName="localBroker">
<xmlmapping>
<cepData>
<a>{a}</a>
<b>{b}</b>
<c>{c}</c>
.
.
<e>{e}</e>
</cepData>
</xmlmapping>
</output>
</query>
Thanks,
KasunW
