How to call multiple queries at the same time?

[dingyo777]

I want to call multiple graphql queries at the same time, something like

{
  first: queryA {
    field1
    field2
  }
  second: queryB {
    field100
    field200
  }
}

How can I do this by DGS framework?
May I get some examples?

I tried to find out it in docs and this github, but I couldn't

Hi we don't support this capability in the DGS framework today.

@dingyo777 I think it is supported in the 6.x versions #426

@TLmaK0 Thank you for sharing! I will try with it. But it seems that generated kotlin codes with gradle task generateJava not applicable with GraphQLMultiQueryRequest.

FYI, my config at kotlin project is as follows:

generateClient = true
generateDataTypes = true
generateKotlinNullableClasses = true
generateKotlinClosureProjections = true

@mbossenbroek Would you give me some guideline or example? My question is how multiple queries or mutations call at once in kotlin2.

[dingyo777]

@srinivasankavitha or do you have a plan to support batch queries or batch mutations in kotlin version with code-gen? Currently, with generated types, projection and DgsClient, it is hard to call mutiple queries or mutations at once.

Hi @dingyo777 - no we don't use this feature at all internally, so will not be prioritizing it.

[mbossenbroek]

Yeah, I never added support for that in the newer kotlin query api, but I am interested in adding it for a use case that I have... That said, I likely won't get around to adding it for a few months, so not sure if that helps you at all :/

@srinivasankavitha @mbossenbroek
Thank you for your answer. 👍 It will be very helpful if batch query or mutation is possible in newer Kotlin version. Not only me but also others who asked this feature previously. :)

I should also note that I'm open to contributions if you'd like to throw up a PR. I'd be more than happy to get you started if you're interested in that route.

@dingyo777 could you confirm that this would work for your needs? https://github.com/Netflix/dgs-codegen/pull/676/files#diff-91edda77a8b25bbc8aa8f2fc0e7f194b330ccca58db4ca1f0adb7aa5b7d123db

This is released now
