Welcome!

```auto
select count(*) from Customer group by Last_Name, First_Name, City

```

Is most likely the same as

```auto
select count(*) from Customer

```

Is that what you want?

But anyway my advice would be first to write the elasticsearch query.  
You can get it by using [the translate API](https://www.elastic.co/guide/en/elasticsearch/reference/current/sql-translate.html) like:

```auto
DELETE customer
PUT customer
{
  "mappings": {
    "properties": {
      "City": { "type": "keyword" },
      "First_Name": { "type": "keyword" },
      "Last_Name": { "type": "keyword" }
    }
  }
}
POST customer/_doc
{
  "Last_Name": "foo", 
  "First_Name": "bar",
  "City": "somewhere"
}
POST _sql/translate
{
  "query": "select count(*) from customer"
}
POST _sql/translate
{
  "query": "select count(*) from customer group by Last_Name, First_Name, City"
}

```

Then adapt the result to the java High Level Rest Client.
