Oracle DB Exporter in Kubernetes: Handling HA and Duplicate Queries

[ankitakhot92]

I'm currently using Oracle DB Exporter to expose database metrics to Prometheus and visualize them in Grafana. I’d like to understand the best-practice approach for setting up High Availability (HA) for the exporter. Currently, I have deployed the Oracle DB Exporter as a Kubernetes Deployment. When I increase the number of replicas (say 3 replicas), each exporter replica independently runs the same SQL queries against the database, which effectively triples the query load. This behavior isn’t ideal, so I’m looking for a recommended solution to achieve HA without adding unnecessary load to the database.
