  • Data Science Summit 2025: Super-fast Access to Unstructured JSON: the ClickHouse® Way

    Maciej Bak - Support Engineer at Altinity - speaks at Data Science Summit 2025. The origins of the Data Science Summit date back to 2014, when the first Data Science Warsaw community meeting was held. It was the popularity of these periodic meetups that contributed to the decision to organize the first edition of the conference, and its success led to subsequent editions. Currently, DSS is the largest Polish community focused around *data* field.
    Maciej's talk - Super-fast Access to Unstructured JSON: the ClickHouse Way is about indexing JSON, which has always been a challenge. Even databases built around documents, like MongoDB, struggle to make unstructured data both flexible and fast. Until now, ClickHouse users had to lean on pipelines, materialized views, or Map hacks to query JSON at scale.

  • San Francisco Meetup: Real Time Data Lakes and AI

    The Open Source Analytics Community is proud to host this meetup in San Francisco. Real-time databases are integrating with data lakes to reduce storage costs and share data with AI and data science. Please join us to hear from a range of experts as they share current problems and solutions while navigating the transition from closed storage models to open table formats like Apache Iceberg.

  • AI-Powered Alert Analysis: Uncovering Critical Patterns in ClickHouse® Databases

    Manual analysis of thousands of daily database alerts is impossible—but AI changes everything.
    This talk demonstrates using modern AI tools to analyze internal alert databases and uncover critical patterns in ClickHouse® Deployments.
    Through live demos, we’ll show how to:
    1. Identify the most critical and common alert patterns using AI-assisted SQL generation
    2. Correlate application alerts with ClickHouse® system tables (query_log, part_log, asynchronous_metric_log)
    3. Automate root cause analysis and predict alert escalation paths
    4. Transform raw alert data into actionable insights for proactive monitoring
    See how combining ClickHouse®’s analytical power with AI tools creates a modern framework for database monitoring that prevents production outages before they happen.

  • Open Source Summit + AI_dev: Open Source GenAI & ML Summit  + Automotive Linux Summit Japan 2025: OTel Me How To Get My Open Source Community Taken Seriously: Lessons Learned as an OTel Maintainer

    One of the core parts of any open source project is community – after all, you need people to write the code, and people to use the code. However, you also need people to: raise awareness about the project, drive the adoption and implementation of the project, and to connect these intersecting groups.
    In this session, Josh and Adriana will share how they support and help build the OpenTelemetry (OTel) community through their work as a Maintainer of the End User SIG, including:
    * Improving the project via collaborations with other OTel SIGs
    * Driving contributions to the project
    * Demonstrating business value to end users
    * Driving adoption through connecting end users and contributors.
