ElasticSearch from SQL DB
Why is there no such DataImportHandler thing in ElasticSearch? Uhm, well ... but because:
1. You should really consider your own scripts
(be it jvm based, perl, ruby, php, nodejs/javascript)
to feed ElasticSearch via bulk indexing:
http://www.elasticsearch.org/guide/reference/java-api/bulk.html
2. There are two projects doing it already:
* http://code.google.com/p/sql-to-nosql-importer/
* https://github.com/Aconex/scrutineer (keeps DB in synch with ES or solr!)
