I generated xml and protobuf messages and it seems Protobuf message is 3.5
times smaller than xml for my project.
I am very satisfied :)
However when it comes to *performance, I think I did something wrong..*
I use Spring boot and I have the following methods for Jmeter test.
The XML method below is 4-5 times faster than the Protobuf method.
@RequestMapping(value = "/getpbmsg")
@ResponseBody
ProtobufGeneratedFile.Pojo getPbMsg(@RequestBody Pojo pojo) throws
IOException {
PojoToProtobufConvertor pbParser = new PojoToProtobufConvertor(pojo);
return pbParser.convertInboxPojo();
}
@RequestMapping(value = "/getxmlmsg",
produces=MediaType.APPLICATION_XML_VALUE)
@ResponseBody
Pojo getXmlMsg(@RequestBody Pojo pojo) throws IOException {
return pojo;
}
I convert a pojo to a ProtobufGeneratedFile.Pojo object.
'ProtobufGeneratedFile' file was generated by 'protoc.exe'.
I produced a protobuf message in the following way,
ProtobufGeneratedFile.Pojo.newBuilder()
.setName(pojo.getFocusId())
.setTitle(pojo.getTotalMsgs())
.addAllMessage(
pojo.getMessages().stream().parallel()
.map(pojoMsg ->
ProtobufGeneratedFile.Pojo.Message.newBuilder()
.setDate(pojoMsg.getDate())
.build())
.collect(Collectors.toList());
).build();
I am wondering if this is the most optimized way.
I think there is a better way to convert a pojo to a protobuf message.
