Dear Wiki user, You have subscribed to a wiki page or wiki category on "Solr Wiki" for change notification.
The following page has been changed by HossMan: http://wiki.apache.org/solr/SolrCaching The comment on the change is: Solr is not an acronym ------------------------------------------------------------------------------ - = SOLR Caching = - [[TableOfContents]] = Overview = - SOLR caches are associated with an Index Searcher — a particular 'view' of the index that doesn't change. So as long as that Index Searcher is being used, the items in the cache will be valid (as long as the cache doesn't get too full) and will be available for reuse. Caching in SOLR is unlike ordinary caches in that SOLR cached objects will not expire after a certain period of time; rather, cached objects will be valid as long as the Index Searcher is valid. + Solr caches are associated with an Index Searcher — a particular 'view' of the index that doesn't change. So as long as that Index Searcher is being used, the items in the cache will be valid (as long as the cache doesn't get too full) and will be available for reuse. Caching in Solr is unlike ordinary caches in that Solr cached objects will not expire after a certain period of time; rather, cached objects will be valid as long as the Index Searcher is valid. The ''current'' Index Searcher serves requests and when a ''new'' searcher is opened, the new one is auto-warmed while the current one is still serving external requests. When the new one is ready, the current one first finishes the requests it is handling, then the system switches to the new, warmed searcher and the current one is discarded. This we call, "registered"—when a searcher becomes the current searcher to handle queries. The current Searcher is used as the source of auto-warming. When a new searcher is opened, its caches may be prepopulated or "autowarmed" using data from caches in the old searcher. For more information on autowarming and caching, see the Cache Considerations section on the SolrPerformanceFactors page. @@ -77, +75 @@ == User/Generic Caches == - User who have written custom SOlr plugins for their applications can configure generic object caches which Solr will maintain and autowarm using whatever regenerator is configured for them. + User who have written custom Solr plugins for their applications can configure generic object caches which Solr will maintain and autowarm using whatever regenerator is configured for them. {{{ <!-- Example of a generic cache.
