[jira] [Comment Edited] (SOLR-11581) NoMergeScheduler ctor should
be public for allowing instantiation from SOLR
[ https://issues.apache.org/jira/browse/SOLR-11581?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16234474#comment-16234474 ]

Thanks Amrit, and Michael.
I am already doing most of what you are recommending. I want to write a blog on it, once I successfully upgrade to solr 7 and also look forward to your Amrit's article. -Though, we don't use "useCompondFile" for the sake of better query performance. - (EDIT, I later found that this perception is wrong)
Michael: In our current design, we bulk index all the accumulated documents, then merge explicitly to an optimal number of segments (10 or so). Only then we start live indexing and query traffic to the servers (there are some intermediate steps to replace solrconfig and also index for the time taken during bulk indexing). In earlier experiments with older Solr versions, keeping merging ON while bulk indexing slowed down the whole process.

> Security Level: Public(Default Security Level. Issues are Public)
> Reporter: Nawab Zada Asad iqbal
> Priority: Minor

> There are scenarios where a SOLR user may want to use NoMergeScheduler. However, it is not possible to use it today, since its constructor is private and solrconfig.xml requires a Scheduler with public constructor.
