5 years ago An alternative would be to use the dsl-json (de)serialiser (https://github.com/ngs-doo/dsl-json). This claims to be on par with binary formats for performance but is human readable. This would also make it easier for other things to generate stat events as it is just plain old json.
On profiling, a lot of time is spend unmarshalling the xml. If stroom were to put stat events on kafka in something like flatuffers then the serde cost could be reduced. There also appears to be a noteable cost in converting the datetime in the xml into a java instant. The downside to flatbuffers is the added complexity, inability to human read the messages on the topic.
