DoubleMax Aggregation not supported

[Shabhana]

We have druid-query like below:

var q5 = client.groupBy()
q5.dataSource('stmp_dlv_1')
q5.granularity('month')
q5.dimensions(['txn_mth'])
q5.aggregation('doubleSum', 'GROSS', 'sum_gross')
q5.aggregation('doubleMax', 'NTPV', 'max_global_ntpv')

q5.exec(function(err, result) {
  if (err) {
    // handle error...
    console.log("*****error*****",err)
  }
  else {
    console.log("******result****",result);
  }
})

Getting below error :

/Users/srajathii/Documents/hikma/Site/node_modules/druid-query/lib/fields/aggregations.js:51
    throw new FieldError('Unknown aggregation type: ' + type)
    ^

Also tried q5.aggregation('max', 'NTPV', 'max_global_ntpv')

getting same error.

Can you please help with a way to find the max value of the metric?

Same goes for floatMax, no support there either.

I think this library is largely incomplete and doesn't support features in the latest druid (0.20)

fwiw, I ended up abandoning this library and moving over to Imply Ply and using druidRequestor outside of Ply for JSON queries, which returns promises. It seems to be far more supported.
