Hmm, I am not an expert but IMO that should not go directly to the DirectUpdateHandler. Solr is following the push model for updates till now. The above is changing this since now solr is pulling the documents to add from the db. Not saying this is bad or good. I think you should consider something like this: DbToSolrXml.java -> this component connects to the db and generates proper solr xml update statement. From here you do as usual. Have a look at https://issues.apache.org/jira/browse/SOLR-66 maybe you can use this. HTH salu2 > > thanks > ryan
