How contrib for solr memcache query cache
Hi all:
I want to contrib memcache implement solr cache (only test query result cache)
patch for solr 1.3 http://code.google.com/p/solr-side/issues/detail?id=1&can=1
solr-memcache.zip http://solr-side.googlecode.com/files/solr-memcache.zip
=====================readme.txt=========================
MemcachedCache instead of solr queryresultCache (default LRUCache)
config in solrconfig.xml to use solr-memcache
add newSearcher and firstSearcher Listener, such as:
<listener event="newSearcher" class="solr.MemcachedCache" />
<listener event="firstSearcher" class="solr.MemcachedCache" />
use listener only for get index version, to create memcached key
indexVersion is static long field of MemcachedCache.java.
//originalKey is QueryResultKey
memcached key = keyPrefix+indexVersion+"-"+originalKey.hashCode()
<!--
MemcachedCache params:
memcachedHosts (required), "," split.
name (optional) no default.
expTime (optional) default 1800 s (= 30 minute)
defaultPort (optional) default 11211
keyPrefix (optional) default ""
-->
<queryResultCache
class="solr.MemcachedCache"
memcachedHosts="192.168.0.100,192.168.0.101:1234,192.168.0.103"
expTime="21600"
defaultPort="11511"
keyPrefix="shard-1-"/>
dep jar:
memcached-2.2.jar
spy-2.4.jar
solr-memcache.patch for solr 1.3
if download and unzip to d:/apache-solr-1.3.0
copy patch-build.xml and solr-memcache.patch to (d:/apache-solr-1.3.0)
D:\apache-solr-1.3.0>ant -f patch-build.xml -Dpatch.file=solr-memcache.patch
Buildfile: patch-build.xml
apply-patch:
[patch] patching file src/java/org/apache/solr/search/DocSet.java
BUILD SUCCESSFUL
Total time: 0 seconds
if exist d:/apache-solr-1.3.0/contrib/solr-memcache, if no exist you can unzip solr-memcache.zip to that dir
and dist
D:\apache-solr-1.3.0>ant dist
...
look D:\apache-solr-1.3.0\dist\apache-solr-memcache-1.3.0.jar
