At Dailymotion we use Apache Druid to serve our partner-data (views, monetization etc.) Druid is a distributed time-series / column / database with few competitors in the OLAP world. We install our druid cluster on kubernetes with druid-operator. This allows us to easily manage its lifecycle, do automatic rolling upgrade, provide an easy way to scale and use cncf ecosystem for automatic exposition with cert-manager, external-dns and ingress-nginx. However to run our druid setup on kubernetes we had to solve challenges related to availability, metadata and evolutivity. We will present our architectures (past and present) and the technical means we used to install and manage druid on our clusters with an opensource operator, how we optimize our caching with Memcached and caffeine and how we performed a migration with no downtime and no costly backfills. At the end we will explain how we integrate this setup with our gitops workflow , how we realize common operations (vertical/horizontal scaling, updates, monitoring) and what we are working on as the next step for our Druid stack: Ingestion improvements, multi-tenancy and running Druid without Apache Zookeeper
