In this case study I'll discuss architectural lessons learned from refactoring an existing REST-API backed by Apache Solr. The initial goal of the refactoring was to speed up data access while scaling from 5m documents to 20-50m documents stored in Solr. Under consideration was the hosting infrastructure, the REST API Java code and the Solr documents and configuration. In this talk I'll give a brief review of the results.
"Pimping" the Solr configuration, the client access and the document structure achieved better results. But the elementary lesson learned was, that a significant increase of data access speed can only be realized with a functional redesign and a simplification of the REST API. NO CAPS ON CORES & SHARDS) I'll explain how this led us directly to distinct Solr cores and why we dropped the introduction of Solr shards or a breathing cloud infrastructure.
