Subject Re: latency in solr response is observed after index is updated
Date Fri, 04 Dec 2009 16:25:43 GMT

Hi Kay Kay ,
     We have commented out  auto commit frequency in solrconfig.xml

below is the cache configuration:-

    <filterCache
      class="solr.LRUCache"
      size="512"
      initialSize="512"
      autowarmCount="256"/>

   <!-- queryResultCache caches results of searches - ordered lists of
         document ids (DocList) based on a query, a sort, and the range
         of documents requested.  -->
    <queryResultCache
      class="solr.LRUCache"
      size="512"
      initialSize="512"
      autowarmCount="256"/>

  <!-- documentCache caches Lucene Document objects (the stored fields for each document).
       Since Lucene internal document ids are transient, this cache will not be autowarmed.
 -->
    <documentCache
      class="solr.LRUCache"
      size="512"
      initialSize="512"
      autowarmCount="0"/>

will further requests after index is updated  wait for auto warming to complete ?

Thanks,
Bharath
