[jira] Commented: (TUSCANY-1194) Improve SCA SDO databinding serialization performance

Raymond Feng commented on TUSCANY-1194:
---------------------------------------

The databinding-sdo-axiom module provides the direct transformation from SDO to AXIOM. http://svn.apache.org/repos/asf/incubator/tuscany/java/sca/modules/databinding-sdo-axiom/. But if I remember correctly, it requires a newer version of the AXIOM to take the full performance advantage.

We could probably move to the latest AXIOM level as Axis2 1.2 release is on the way out.

> Currently a web service response with SDO databinding is first transformed from SDO to an XMLStreamReader and then to a fuly inflated OM element which is serialized to SOAP/XML.  There are opportunities for two significant performance improvements:  First, use the OMDataSource approach to provide for the possibility of a single transformation and to also eliminate the inflation of the OM element.  Second, directly transform the SDO to SOAP/XML without the intermediate transformation to XMLStreamReader.
