Sunspot-solr 占用了太多内存？什么是减少内存使用的便捷方法？

Question

所以看来 Sunspot-Solr 正在消耗大量内存。这可能是由于我作为程序员分配正确使用它的不当行为。

首先，我不允许太阳黑子自行重新索引。

searchable :auto_index => false do

我相信仅此一项就可以阻止它重新编制索引。相反，我在每天清晨运行一次的 cron-tab 上运行重新索引过程。

我开始这样做的原因是，随着应用程序的扩展，数据似乎在机器上堆积得如此之多，以至于仅仅加载主页就需要相当长的时间。

我做错了什么导致以下错误？还有什么我可以做得更好？

Answer 1

您可以根据当前环境在 config/sunspot.yml 文件中指定最小和最大内存分配，例如

development:
  solr:
    min_memory: 512M
    max_memory: 1G
    solr_jar: /path/to/start.jar
    log_level: DEBUG

文档：http://outoftime.github.com/sunspot/rails/docs/classes/Sunspot/Rails/Configuration.html

Answer 2

max_memory 和 min_memory 在 https://github.com/sunspot/sunspot/commit/74ea3881872398bd14cf6e96481826141ee82c93 中更改为 memory

所以目前的答案应该是：

development:
  solr:
    memory: 1G
    solr_jar: /path/to/start.jar
    log_level: DEBUG

Answer 3

我反转了 Lucene 引擎的执行并强制它使用 64 位 JVM，这允许它完全访问我机器上所有可用内存...

为什么 rake 在 64 位窗口上使用 32 位 JVM 超出了我的理解范围......

我现在使用 sunspot:solr 运行脚本手动执行：

cd \RailsInstaller\Ruby1.9.3\lib\ruby\gems\1.9.1\gems\sunspot_solr-2.1.0\solr\

java -d64 -Djetty.port=8982 -Dsolr.data.dir=C:/[your-project-dir]/solr/data/development -Dsolr.solr.home=solr -Djava.util.logging.config.file=C:/Users/[user-名称]/AppData/Local/Temp/logging.properties20140117 -jar start.jar
