Cao Manh Dat commented on SOLR-8480:
------------------------------------
I'm a new one too. But as Streaming API is getting more and more complicated,
users may have very long running streaming job (ex : parallel update from many
sources ...). So it will be necessary to have these info.

All things are possible I suppose, but right now there's nothing that knows the
size of the result-set.

I use this snippet to get size of SolrStream (JsonTupleStream#advanceToDocs())
{code}
expect(JSONParser.OBJECT_START);
if (advanceToMapKey("numFound", true)){
numFound = parser.getLong();
}
{code}
{quote}
For example, consider: unique(search(...)). How would a UniqueStream define its
size?
{quote}
You are absolutely right. We can change the method to {{ getEstimatedSize() }}.
It is good enough.
