Introduction

Apache Druid is a real-time analytics database that’s used to analyze large amounts of data quickly. It’s designed for use cases that require high uptime, fast query performance, and real-time ingestion.

Kubernetes 2.0 ConfigMap

Users should update or append the existing ConfigMap named opsramp-workload-metric-user-config by adding application-specific fields. These fields may include authentication credentials, collection frequency, and other relevant configurations.
