Subject RE: what happens to docsPending if stop solr before commit
Date Wed, 06 Apr 2011 23:19:16 GMT
Really?  Great!  I was wondering if there was some cleanup cycle like
that which would occur upon shutdown.  That sounds like much more
logical behavior!

Robi,

Usually they are never lost, but they are committed.

When you stop Solr, servlet container (Jetty) calls servlets/filters
destroy() methods. This causes closing all SolrCores. Then
SolrCore.close()
calls UpdateHandler.close(). It calls SolrIndexWriter.close(). Then
pending docs are flushed, then committed.
