mutation code:

mutation updateFollows (
  $updateUsersPermissionsUserId: ID!,
  $data: UsersPermissionsUserInput!,
  ){
    updateUsersPermissionsUser(id: $updateUsersPermissionsUserId, data: $data
    ){
    data{
      id
      attributes{
        follows {
          data {
            id
          }
        }
      }
    }
  }
}

update_parmas is:

{
  "updateUsersPermissionsUserId": 1,
  "data": {
    "follows": [1,2,3,4]
  }
}

if I want push new id 5 to follows,
i can set “follows”: [1,2,3,4,5],
ofcs it worked well,

but my question is:
how to push 5,not renew follows array,

because the old data of follows maybe have follows.length > 10000000000,I can’t get them all and renew a new array and set it

thanks to all
