Re: Performance issue in Query execution in Solr 8.3.0 and 8.5.1

RE: using aliases in topic stream

Joel, I looked at the commits from that enhancement briefly. It looks like the work to resolve te slices was put into a central method in CLoudSolrStream. But to check aliases the Boolean flag needs to be true. Everywhere this is used in TopicStream its set to false (3 places). The first two ar
