AWS Appsync complex subscription arguments

Question

I'm currently working on an messaging app and want to create a global subscription just to demonstrate what I want to achieve Suppose there is a mutation like sendMessage that contains senderId and Members just for example like :-

mutation sendMessage(senderId :String!,members:[String]){
    response
}

This mutation is used to send message to user the real example is different and complex so I'm asking with small example lets run a mutation with the following values like :-

mutation sendMessage(senderId :"A",members:["A","B","C"]){
    response
}

My question - Is it possible to get the subscription only when the members contain "B" in members array something like this :-

subscribeToSendMessage(member:["B"]): message aws_subscribe(mutations: ["sendMessage"])

Answer 1

Currently this is not possible. There's a similar question with good explanation in the AWS forums
