Great question. I do not think there is an API to get that data (someone
please correct me if I am wrong), but since the type is basically just
another field inside the Lucene document, you can also run a
aggregation/facet on the implicit field called \_type:
{
"size": 0,
"query": {"match\_all": {}},
"aggs" : {
"types" : {
"terms" : { "field" : "\_type" }
}
}
}
Cheers,
Ivan

I believe [http://localhost:9200/index/\_mapping](http://localhost:9200/index/_mapping) will give you types.
It is an indirect method for sure, but that kind of metadata is going to be in memory and not require fielddata cache.

Thanks, I guess this may be the perfect solution.

I knew there had to be a simpler solution! Missed the extremely obvious.
