Hi All, Currently APIM is using an internal APIM specific configuration resides in api-manager.xml which include DAS server URL, username, password etc. Those configuration are used to instantiate an org.wso2.carbon.databridge.agent. DataPublisher object, which is then used to publish events directly to streams in DAS.
As it is an APIM specific configuration, it is not reusable by other non-APIM features. Also org.wso2.carbon.databridge.agent.DataPublisher is intended to be used in non-carbon environments, for carbon environments, the recommended way is to use the Event Stream OSGi Service. So we were trying to re-structure APIM data publishing code to use new Event Stream OSGi service explained in [1]. 1. Create all the streams defined in DAS in APIM. 2. Create an *event publisher per each stream *which takes data from the stream and publish to DAS. 3. In each event publisher we need to configure DAS specific configuration. Ex: <?xml version="1.0" encoding="UTF-8"?> <eventPublisher name="test" statistics="disable" trace="disable" xmlns=" http://wso2.org/carbon/eventpublisher";> <from streamName="streamTest" version="1.0.0"/> <mapping customMapping="disable" type="wso2event"/> <to eventAdapterType="wso2event"> <property name="username">admin</property> <property name="protocol">thrift</property> <property name="publishingMode">non-blocking</property> <property name="publishTimeout">0</property> <property name="receiverURL">tcp://localhost:7611</property> <property encrypted="true" name="password">XXXXXXXX</property> </to> </eventPublisher> But we are facing a small problem here; in APIM there are many event streams being used. If there's a change happen to DAS configuration, we need to change it in all the event publishers which makes it difficult to maintain. As per the offline chat with DAS team, this is a current limitation. Are we going to move forward with the existing implementation?
