I have added a JMX testplan

Have you added your Schema or a replica?

I have added the Schema

Hi @nrellanti

Thank you for your collaboration. We are looking at it and we will get back to you as soon as possible.

AdrianLagartera · 2023-02-03T12:54:58Z

Hi @nrellanti , could you add the complete protobuf file as there are missing parts such as the Order.

Thank you.

nrellanti · 2023-02-03T17:16:47Z

@AdrianLagarteraSngular , please see the attached complete messaging_intra_order_proto.txt protobuf file referencing in the messaging_unified_order_proto.txt

AdrianLagartera · 2023-02-14T11:35:43Z

@nrellanti Sorry for the delay, checking the messaging_intra_order_proto.txt file there are some references to classes that it does not have, could it be that it is a schema in a previous version?

For example in the messaging_unified_order_proto.txt the first reference to the .demo.Order.CustomerAccount class does not exist in the messaging_intra_order_proto.txt file

nrellanti · 2023-02-14T16:45:43Z

@AdrianLagarteraSngular ,
Here is the corrected messaging_intra_order_proto.txt file

Added a trim statement to avoid problem when cast the schemas from classpath

Removed some unused test files

AdrianLagartera · 2023-03-01T16:45:00Z

@nrellanti Hi, we have added some changes in the attached branch to fix the problem, to avoid errors, if you are using schema registry to find the file, the subject and the filename must have the same name, in next versions we will fix this so the subject can be different from the filename and it will still work.

On the other hand if you don't use schema registry you can indicate the classpath in jmeter and it will also work without schema registry, just put the files you use in the same folder.

Best regards and thank you very much

vishaldhanani · 2023-03-02T16:17:43Z

Hi @AdrianLagarteraSngular , Thanks for sharing the information and trying to work around this issue.
Basically, We're following the standard practices to register this schema the way @nrellanti has shared two schema files.
We're using TopicNaming Strategy to create topics and schema in the confluent cloud.

Example:
Topic name: MESSAGING-UNIFIED-ORDER
Subject name of parent schema: MESSAGING-UNIFIED-ORDER-value
Child schema's subject name: messaging_intra_order.proto (We are importing this schema in the above parent schema as import "messaging_intra_order.proto";)

We're importing child schema like this because we have seen standard practices for google's well-known schema also registering the same way and importing in any schema.

In the same way, we're importing other custom or child schemas into the parent schema.

The latest Kloadgen jar is not supporting this use case. Can you please advise on the above scenario?

Thank you,
Vishal

Apparently the original project was renamed into cmak to avoid break the TOS of kafka having the kafka in the name of unofficial tool

AdrianLagartera · 2023-03-08T16:08:31Z

Hi, sorry for don't answer before

Using the given params you put on your last message @vishaldhanani I will put the steps you need to do to cover your scenario:

First of all compile the KloadGen from the attached brand: https://github.com/sngular/kloadgen/tree/332-comsngularkloadgenserializerprotobufserializer-nullpointerexception (Currently not in master because we wait until you can confirm it's working in your scenario)
When you pass your schema in your schema registry, be sure your schema have the same root name subject as your file, using the example, subject: messaging_intra_order, name: messaging_intra_order.proto The references of the schema should be like this:

 {
    "schema": "..."
    "schemaType": "PROTOBUF",
    "references": [
    {
      "name": "messaging_intra_order.proto",
      "subject": "messaging_intra_order",
      "version": 1
    }]
}

And after that ensure your topic have the same name as the subject of the schema registry, in the example value you give the subject name of the parent not correct if your topic name its: MESSAGING-UNIFIED-ORDER, should be exactly the same name in the subject and the topic
And finally check if your plan test have the correct Name Strategybecause in the attached one the strategy was RecordNameStrategy instead of the TopicNameStrategy

Let me know if it has been useful for you, or if you find new issues, and thanks for your patience.

vishaldhanani · 2023-03-09T22:17:00Z

Hi @AdrianLagarteraSngular, Thank you for sharing the complete process. Basically, Google's well-known schema is registered as below, and based on those schemas we are following the same process to register custom schema. I think we cannot change this process to register all custom schema for only testing purposes the way you have shared in the above response.

Looking forward if you can handle this kind of use case in the Kloadgen plugin.
{
"schema": "..."
"schemaType": "PROTOBUF",
"references": [
{
"name": "messaging_intra_order.proto",
"subject": "messaging_intra_order.proto",
"version": 1
}]
}

Thank you,
Vishal

alfredo9f · 2023-03-16T17:12:55Z

Hi @vishaldhanani ,

We are taking a look at your last answer, sorry for the delay.
Best regards.

alfredo9f · 2023-03-21T14:51:24Z

Hi @vishaldhanani ,

We have introduced a fix to get the subject from the subject of the reference, so your scenery should be processed correctly. Please, could you check if this solution is valid for you?

Thanks in advance.
Best regards

vishaldhanani · 2023-03-22T20:06:10Z

Hi @alfredo9f, I appreciate your reply. We'll check the most recent changes and let you know if there are any problems.

Thank you,
Vishal

nrellanti · 2023-03-23T14:50:57Z

Hi @alfredo9f ,
Tested the new code from Branch 332-comsngularkloadgenserializerprotobufserializer-nullpointerexception

Getting below error

2023-03-23 09:32:31,932 ERROR c.s.k.l.i.ProtobufLoadGenerator: Please make sure that properties data type and expression function return type are compatible with each other
io.confluent.kafka.schemaregistry.client.rest.exceptions.RestClientException: Subject 'MESSAGING-UNIFIED-ORDER' not found.; error code: 40401.

Please suggest!

alfredo9f · 2023-03-23T15:06:40Z

Hi @nrellanti ,

Please, could you tell me if you have the schema 'MESSAGING-UNIFIED-ORDER' loaded in your schema registry and what 'Strategy Name' are you using in your test?

Thanks in advance.

vishaldhanani · 2023-03-23T19:14:03Z

Hi @alfredo9f, Yes, I also tested with the latest changes and got the same error as @nrellanti getting it.

We are using TopicNameStragtegy to register the schemas and we already have registered schemas for MESSAGING-UNIFIED-ORDER topic.

Please advise!

Thank you,
Vishal

alfredo9f · 2023-03-27T15:04:43Z

Hi @vishaldhanani ,

We did a small fix so now should works. Please, could you check if now is ok for you?

Thanks in advance!

nrellanti · 2023-03-27T15:38:09Z

@alfredo9f ,
Looks like the new fix was working as expected.
I will test few more similar proto files and will confirm.
Thanks for fix !

alfredo9f · 2023-03-27T15:47:48Z

Hi @nrellanti ,

Thanks to all for the checks. We will wait your confirm :)

nrellanti · 2023-12-19T17:19:04Z

Hello @jemacineiras , yes it is failing, I checked both in windows and Mac machines with latest version of JMeter 5.6.2. Could you please have a look the logs posted in the previous chat.

I will test next week and get back to you the updated result

can you pease re attach the jmx file since the previous was lost? it seems something is missing or is not right configured.

Cheers.

Hi @nrellanti,

This error is with the code I just pushed today ?
Its happening with the JMeter 5.6.3 version. Is this the one you are using?

Cheers

nrellanti · 2024-01-26T15:51:20Z

Hello @jemacineiras ,

Just couple of minutes ago, I pulled the code and generated jar file and executed on JMeter version 5.6.2.

However, I have not tested on JMeter 5.6.3. I will test on JMeter 5.6.3. Will update results in a couple of minutes.
Thanks

jemacineiras · 2024-01-26T15:59:54Z

Hi @nrellanti,
Ok I´ll took a look and back asap.

Cheers

Hi @nrellanti
Just uploaded a quick fix, can you try if that works with you in your systems?
Cheers

Still getting more errors.

jemacineiras · 2024-01-30T14:39:42Z

Hi @nrellanti,

still don´t get it.. that imported proto is in the classpath but for any reason looks like is not find it. Will keep digging.
