Simple count() without all nodes, just the value, how??

How to create a query in Hasura which returns the aggregated value only? I need to add a condition from the nested table but I don't want to return all the nested nodes.

My SQL is:

SELECT COUNT(DISTINCT persons.id) 
FROM persons
  INNER JOIN addresses ON persons.id=addresses.person_id
WHERE addresses.country='IE'

I can create only something like this:

query MyQuery {
  persons_aggregate {
    aggregate {
      count(distinct: true, columns: id)
    }
    nodes {
      addresses(where: {country: {_eq: "IE"}}) {
        id
      }
    }
  }
}

How to get rid of all nodes objects from the result? The number or nodes in my case is huge and it is killing Hasura server.

OK, just found it :) Hasura is great!

query MyQuery {
   persons_aggregate(where: {addresses: {country: {_eq: "IE"}}}) {
    aggregate {
      count(distinct: true, columns: id)
    }
  }
}
