Allow firstSearcher and newSearcher listeners to run in multiple threads
------------------------------------------------------------------------
Key: SOLR-3197
URL: https://issues.apache.org/jira/browse/SOLR-3197
Project: Solr
Issue Type: Improvement
Reporter: Lance Norskog
SolrCore submits all listeners (firstSearcher and newSearcher) to a java
ExecutorService, but uses a single-threaded one.
line 965 in the trunk:
{code}
SolrCore.java around line 965: final ExecutorService searcherExecutor =
Executors.newSingleThreadExecutor();
line 1280 in the trunk:
SolrCore.java around line 1280 runs first the, and then the first and new
searchers, all with the searcherExecutor object created at line 965.
Would it work if we changed this ExecutorService to a thread pool version? This
seems like it should work:
{code}
java.util.concurrent.Executors.newFixedThreadPool(int nThreads, ThreadFactory
threadFactory);
{code}
