[jira] [Created] (SOLR-12098) Document the Lucene spins
auto-detection and its effect on CMS dynamic defaults
Shalin Shekhar Mangar created SOLR-12098:
--------------------------------------------
Summary: Document the Lucene spins auto-detection and its effect on CMS dynamic defaults
Key: SOLR-12098
URL: https://issues.apache.org/jira/browse/SOLR-12098
Project: Solr
Issue Type: Task
Security Level: Public (Default Security Level. Issues are Public)
Components: documentation
Reporter: Shalin Shekhar Mangar
Fix For: 7.3, master (8.0)
Lucene auto-detects whether the underlying directory is on a rotational or SSD type disk and based on that it sets defaults for ConcurrentMergeScheduler. We should document this and the system property based workaround in the Taking Solr to Production page (and perhaps also in solrconfig.xml sections)
