At Allegro we use Solr as our main search engine. Due to the traffic to our search engine being thousands of requests per second and index size on the order of a hundred million documents we need to develop custom optimizations. In this post I will describe the story of our Solr plugin development.
At Allegro we use many open-source tools that support our work. Sometimes we are not able to find what we want and this is a perfect moment to fill the gap and to share with the community. We are proud to announce an initial release of Elasticsearch reindex tool — a tool that provides an easy way to rebuild indexes in elasticsearch.
