Moving ingestion from 3 hours to 5 minutes – Challenges and Mitigations

This is a real world account from a Druid cluster in production. A story of 48 hours of debugging, learning and understanding Druid better, filing a couple of issues in Druid github and finally a stable production pipeline again thanks to the Druid community. We will discuss the bottlenecks we had in overlord, slot issues for Peons in middle managers, coordinator bottlenecks, how to mitigated task and segment flooding, what configs we changed sprinkled with real world numbers and snapshots from our graphana dashboards. Finally we will list all the latest awesomeness in Druid 25.0 that helped us in this endeavour, how we discovered those midnight and our learnings.
