Subject Re: Indexing timeout issues with SolrCloud 7.1
Date Thu, 01 Mar 2018 19:20:47 GMT
Thanks Erick. I found an older mailing list thread online where someone had similar issues
to what I was experiencing (http://lucene.472066.n3.nabble.com/SolrCloud-delete-by-query-performance-td4206726.html
<http://lucene.472066.n3.nabble.com/SolrCloud-delete-by-query-performance-td4206726.html>).

I decided to try and rewrite our indexing code to use delete by ID as opposed to delete by
query (we deployed it today) and it appears to have significantly improved the indexing performance
and reliability of the replicas.
