Executing stored procedure through Python NativeAPI

I'm looking into finding ways to  fetch data from cache efficiently and work with it with python - specially pandas.

i tried the following but i'm wondering if this is the most efficient way?

to run the stored procedure as %ResultSet inside cache in a classmethod and serialize the data to JSON

and then call that class method from python

 Class User.RegObj Extends %RegisteredObject
{ ClassMethod runAlpha() As %Library.DynamicAbstractObject
{
set QHi=##class(%DynamicAbstractObject).%FromJSON("{}") set rs=##class(%ResultSet).%New("User.Person:alpha")
set pr=rs.Execute("","") set idx=0 
while rs.Next() {
set idx=$I(idx) 
Set miniList=##class(%DynamicAbstractObject).%FromJSON("{}") 
do miniList.%Set(1,rs.Data("name"))
do miniList.%Set(2,rs.Data("DB")) 
do QHi.%Set(idx,miniList) 
}
return QHi.%ToJSON()
} }

call from Python

>>> import irisnative as iris
>>> conn=iris.createConnection("127.0.0.1", 51773, "USER", "_SYSTEM","SYS")
>>> wrk=iris.createIris(conn)
>>> print(wrk.classMethodValue("User.RegObj","runAlpha"))
{"1":{"1":"adel","2":"62116"},"2":{"1":"adam,2019-01-01","2":"62116"},"3":{"1":"nadam^2019-01-01","2":"62116"},"4":{"1":"nadam:2019-01-01","2":"62116"},"5":{"1":"madam","2":"62116"},"6":{"1":"jadam","2":"62116"},"7":{"1":"qadam","2":"62116"}}

the JSON can be further manipulated to a pandas dataframe.
