Sammy Yu updated CASSANDRA-423:
-------------------------------
Attachment: 0001-CASSANDRA-423-Committed-first-version-using-Solr-s-C.patch
Attached is initial version of the patch using SOLR's LRUConcurrentCache.
There are some opened questions. One regarding how to configure the cache, it
has a lowWatermark and acceptableWaterMark, I've made some questionable code to
allow this to use KeysCachedFraction. If size is less than 0, force key size to
1 and lowWaterMark to 0.
There's also a second hack which calls destroy on construction of keycache this
is because by default the finalize() method will log an error message if the
destroy has been set.
See code at
http://svn.apache.org/viewvc/lucene/solr/trunk/src/common/org/apache/solr/common/util/ConcurrentLRUCache.java?view=markup
> add new LRU cache
