<!-- Solr Internal Query Caches
|
||
|
|
|
||
|
|
There are two implementations of cache available for Solr,
|
||
|
|
LRUCache, based on a synchronized LinkedHashMap, and
|
||
|
|
FastLRUCache, based on a ConcurrentHashMap.
|
||
|
|
|
||
|
|
FastLRUCache has faster gets and slower puts in single
|
||
|
|
threaded operation and thus is generally faster than LRUCache
|
||
|
|
when the hit ratio of the cache is high (> 75%), and may be
|
||
|
|
faster under other scenarios on multi-cpu systems.

||
|
|
-->
|
||
|

<!-- Filter Cache
|
||
|
|
|
||
|
|
Cache used by SolrIndexSearcher for filters (DocSets),
|
||
|
|
unordered sets of *all* documents that match a query. When a
|
||
|
|
new searcher is opened, its caches may be prepopulated or
|
||
|
|
"autowarmed" using data from caches in the old searcher.
|
||
|
|
autowarmCount is the number of items to prepopulate. For
|
||
|
|
LRUCache, the autowarmed items will be the most recently
|
||
|
|
accessed items.
|
||
|
|
|
||
|
|
Parameters:
|
||
|
|
class - the SolrCache implementation LRUCache or
|
||
|
|
(LRUCache or FastLRUCache)
|
||
|
|
size - the maximum number of entries in the cache
|
||
|
|
initialSize - the initial capacity (number of entries) of
|
||
|
|
the cache. (see java.util.HashMap)
|
||
|
|
autowarmCount - the number of entries to prepopulate from
|
||
|
|
and old cache.
|
||
|
|
maxRamMB - the maximum amount of RAM (in MB) that this cache is allowed
|
||
|
|
to occupy. Note that when this option is specified, the size
|
||
|
|
and initialSize parameters are ignored.

then documents 0 through 49 will be collected and cached. Any further
