There is a 1-second latency between ivy.repo.save(object) and ivy.repo.search(Object.class)

vagabond — Fri, 22 Feb 2019 01:16:25 -0500

Hi Axon.ivy Team,

Given the snippet of code:

Person p = new Person();
p.id = UUID.randomUUID().toString();
p.name = "John Doe";
p.birthdate = LocalDate.now();

ivy.repo.save(p);

Object result = ivy.repo.search(Person.class)
    .textField("id").containsPhrase(p.id)
    .execute().getFirst();

ivy.log.error("HHH - it is null " + #result);

Thread.sleep(TimeUnit.SECONDS.toMillis(1));

result = ivy.repo.search(Person.class)
    .textField("id").containsPhrase(p.id)
    .execute().getFirst();

ivy.log.error("HHH - it is null " + #result);

I found that there was a 1-second latency between the call to ivy.repo.save() and ivy.repo.search(). This is super annoying because we had to wait for 1-second every time until the saved object can be searched via the API. Blocking the execution for 1-second to wait until it is indexed to ES every time we save the object into the BusinessDataRepository is a terrible hack.

Is it by design? Can this be fixed so that the two calls work?

P.S: Please don't advise me to use the returned BusinessData id because it doesn't address my issue. I want to search back the data I save based on the object's field, not fetching it again.

P.P.S: Tested with Axon.ivy Designer 7.2.1 on my local workstation.

UPDATE

25.2.2019:

In our project, we were able to develop RESTful API for other parties. As we already have persisted our objects (for example Dossier), in BusinessDataRespository, we would want to preserve that behavior.

An excerpt from of our OpenAPI spec:

paths:
  /dossiers/{dossier_id}/persons/:
    post:
     operationId: addPersonToDossier
      description: add a single person into an existing Dossier
      requestbody:
        'application/json':
          schema:
            $ref: '#/components/schemas/Person'
      responses:
        '201':

    get:
      operationId: getAllPersonsInDossier
      description: get *all* existing persons of an existing Dossier
      responses:
        '200':
          content:
            'application/json':
              schema:
                type: array
                items:
                  $ref: '#/components/schemas/Person'

From our client, after they have already invoked several calls to addPersonToDossier, they may want to invoke getAllPersonsInDossier to fetch all Persons of a Dossier.

We persists Person separately from our Dossier to avoid ConcurrentModificationException, each Person holds a reference to its Dossier. Now in order to implement getAllPersonsInDossier, we have to use Ivy.repo().search(..).

Unfortunately, due to the 1-second latency, calling getAllPersonsInDossier too soon will probably return an empty result. This forces us to either:

Require our clients to WAIT on their side for 1-second until they can call getAllPersonsInDossier.
On the server side, we somehow have to implement a while loop to check until the Person could be found via search API, then we consider the addPersonToDossier finishes (or worse, a Thread.sleep(1000)).

Cannot use BusinessDataRepository in JAX-RS resources

vagabond — Thu, 24 Jan 2019 00:49:27 -0500

Hi Axon.ivy team,

I know this questions had been asked long time ago at https://answers.axonivy.com/questions/2777/can-not-use-ivy-repo-in-resfulapi. But the question was for Axon.ivy 6.3.0 and there was never a resolution of the issue.

I am using Axon.ivy 7.0.8 LTS and I still encountered the same issue.

I introduce a JAX-RS resource:

package com.example.lab;

@PermitAll
@Path("awesome")
public class TheAwesomeApi {

    @POST
    @Consume("application/json")
    @Produces("text/plain")
    public String saveAwesomeMessage(AwesomeMessage message) {
        return Ivy.repo().save(message).getId();
    }

    public static class AwesomeMessage {
        private String content;
        // getter, setter
    }
}

When I tried to call this API, the exception was returned.

curl http://localhost:8081/ivy/api/designer/awesome \
  -H 'Content-Type: application/json' \
  -d '{ "content" : "This is an awesome message" }'

full stacktrace can be found here: https://pastebin.com/hXcyQq6h

2 errors"

Is this issue still a known limitation even with the 7.0 LTS?

Thanks for your support!
