This talk shares how Yelp has scaled it’s Elasticsearch-based search backend into a Ranking Platform. We will start with the challenges on the indexing side and how we have developed a clean & extensible Flink-based Ingestion API for Elasticsearch. We will discuss how we improved reliability by building a gate-keeper for safeguarding our Elasticsearch clusters. Finally, we will share how we monitor, manage and safely rollout cluster-level changes.
