RE: [Solr8.7] Performance of group.ngroups ?

[Bruno Mannina]

Hello,



I found a temporary solution to my problem.



I do a request without ngroups=true => result is quickly

And just after, I do a simple request with my query and this param:

….&json.facet={x:"unique(fid)"}

Where the field « fid » is my group field name.



88 sec => 3~4 sec for both requests.



Regards,

Bruno

Objet : [Solr8.7] Performance of group.ngroups ?



Hi All,



I have more than 130 million documents, with an index size of more than
400GB on Solr8.7.



I do a simple query and it takes around 1400ms, it’s ok but when I use
ngroups=true, I get an answer in 88sec.

I know it’s because Solr calculates the number of groups on a specific field
but is exist a solution to improve that? An alternate solution?



Many thanks,



Cordialement, Best Regards

Bruno Mannina
