Getting solr source count without using search query every time

Hi All,

I am using solr cloud environment to search and index the data.

Example

Source_field_s:

A,

B,

C,

 etc


Expected result:

A(100)

B(200)

C(50),

etc




Data stored in solr.  Every second or 10 seconds i need to get source 

facet( A,B,C) to produce statistics. I do not want to disturb production
solr for this facet as it is already serving end user request and indexing
data.


i read about CDCR approach, could use CDCR(Target) to get only statistics
where as it is waste of storage. I do not worry about the data and concern
about count of all sources.


is there any internal approach available to get Stat or facet about
source_field for every second or batch whenever there is update in
index(add, delete and update).


Like CDCR, is there a way to get only source count(facet query result)
update to target in sync with source solr.


Could you please provide a approach to handle this problem?

Thanks,
