Subject Re: Solr Streaming Queries Performance Issues [v7.2.1]
Date Fri, 28 Sep 2018 17:08:05 GMT
Hey Guys,

This is the sample query I am making:


curl http://localhost:8983/solr/collection_name/stream -d
'expr=facet(collection_name,q="id:953",bucketSorts="week
desc",buckets="week",bucketSizeLimit=200,sum(sales),sum(amount),sum(days))'


Also in my collection, I have almost 10 Billion documents with many
deletions (close to 40%). I was planning to run optimise to merge the
segments but spoke to admin team and lucidworks guys and they were against
it saying that it will make very large segment file. Is it true that
optimise in solr should not be used, as it comes with other issues?

Thanks
