Recent changes in Russian federal law require organizations to submit tax information in electronic form. Federal Tax Service of Russia revises this information and sends automatically generated claims. “Kontur.NDS+” project helps businesses to perform this revising in the cloud before tax documents are submitted to the Federal Tax Service. “Kontur.NDS+” is built on Hadoop stack (which is quite common), sharded and replicated Solr (which is quite common too, but required some tuning) and Perl (which is not common at all). The project evolved the last 1.5 years and this evolution is a subject of current presentation.
