19:00 Event start & Welcome Speech

19:05 📣 Dainius Jocas, Vinted - Don't change partition count for Kafka topics!

I'll tell a story on how we've hunted down a Heisenbug in a systems that should prevent it by design in the very first place and finally fixed it. The story involves Kafka, Kafka Connect, Elasticsearch, optimistic concurrency control, data inconsistencies, and SRE with plenty of good intentions that in a series of unfortunate circumstances caused the nasty bug.
I advice to read this blog post as an introduction to the talk https://vinted.engineering/2021/01/12/elasticsearch-indexing-pipeline/.

19:45 📣 Łukasz Szczęsny, Chronosphere - M3 and Prometheus: Monitoring at scale for everyone

For the past few years, Prometheus has solved many people’s monitoring needs, and it’s exceptional at what it does. Prometheus has exploded in popularity, and now many wish to store more metrics at longer retention and establish a single pane of glass on top of Prometheus for their monitoring needs across regions.

M3, first developed at Uber, is an open-source metrics platform that you can deploy and run using Kubernetes and Helm that integrates with Prometheus. It can store petabytes of metrics data with replication for high availability in a cost-efficient manner, with compaction-averse time series storage, and an index that can efficiently index and run dimension-based regexp queries on billions of metrics.
