Good monitoring tells you when something is bad. But what about the problems that never trigger an alert? Diana Todea (VictoriaMetrics) is at #bbuzz26 to talk about finding those anomalies before they become incidents.

Observability’s Sixth Sense: Detecting Anomalies in Metrics

In this talk, we look at anomaly detection as a complementary way of working with metrics. Instead of relying on predefined limits, anomaly detection focuses on identifying behavior that deviates from what is normally observed over time. The focus is on how developers can interpret these signals, where anomaly detection is useful, where it is [...]

Search is Back: Solving the “Context Crisis” for AI Agents

Why do smart agents make dumb mistakes? The culprit is context, an old problem with new solutions. Let's fast-forward through 20 years of search evolution to fix the missing link in today’s Agentic AI. We’ll demonstrate how to combine Knowledge Graphs and Vector Search to build reliable, context-aware applications using open-source tools.

From OLTP to OLAP: Is PostgreSQL Eating Analytics Too?

Can PostgreSQL become a serious analytics engine? With emerging columnar extensions, PostgreSQL is pushing beyond OLTP into OLAP territory. This talk explores the current columnar landscape, architectural trade-offs, and how far PostgreSQL can go compared to analytical engines like ClickHouse.

Building a Local News RAG: The Quest for Trustworthiness

We will show you how we build a local newspaper rag and all the problems that came along the way. From trustworthiness to customer wishes, search optimization and generation problems. Local villages, that LLMs know nothing about, content that is semantically the same and outdated information are only a part of the journey we made.

Sunset for the Wild West: Making ML disciplined by default

Many novel machine learning techniques started as clever hacks that just happened to work, but the demands of building real systems can be at odds with this creative culture. Learn about our open-source stack to improve quality-of-life for ML researchers and infrastructure teams alike — and how their concerns aren't as different as you might [...]

Bias in datasets doesn't always announce itself, by the time a model fails, the damage is done. At #bbuzz26, Stas Don will show how to catch it before it ever gets that far.

Detecting Hidden Bias in Datasets Before Models Fail

Hidden bias in datasets silently breaks machine learning systems in production. This talk shows how to detect data imbalance, leakage, and coverage gaps early using practical metrics, visualizations, and open-source tools—before misleading offline metrics turn into costly real-world failures.

Real-Time ML Pipelines: Feature Chaining with Chronon

Modern ML applications demand features computed in near real-time with sub-100ms latencies. This talk dives into Chronon, an OSS feature platform bridging streaming data infrastructure and production ML. Using a two-tower search pipeline example, we'll show how we can chain embeddings with tabular features while minimizing hot-path computation.

Floe: Policy-Based Table Maintenance for Apache Iceberg

Iceberg maintenance procedures work. Orchestrating them across hundreds of tables is the problem. Floe is an open-source system that treats maintenance as policy: glob patterns, schedules, and health-driven triggers that gate operations on real table metrics. Supports 7 catalogs, executes via Spark or Trino.
