🎤 Session Details: Pushdown or pay up: predicate pushdown in pg_clickhouse
Description: A cloud bill that still hurts is the best teacher. This talk is built around a real federation failure involving AWS Athena and Redshift, where missing predicate pushdown created a triple-cost disaster: full table scans, unfiltered S3 dumps, and a lifecycle policy no one remembered to set. From that war story, we move into a practical examination of cross-engine federation with ClickHouse, including when to use a Postgres-compatible interface like pg_clickhouse versus querying directly, how to verify pushdown behavior using EXPLAIN VERBOSE, and what the v0.2.0 HTTP streaming improvement means for memory pressure in production. You will leave with a concrete checklist for trusting any cross-engine query pattern before it trusts itself with your budget.

Lakes to Queries: Building High-Performance Data Platforms
Location not specified yetJoin us for a community meetup exploring how modern teams are rethinking data architecture from the ground up.Join us for a community meetup exploring how modern teams are rethinking data architecture from the ground up. From designing scalable data lakes to building fast, reliable query layers on top of them, speakers will share real production experiences and practical lessons learned along the way. Whether you are architecting a new data platform or evolving an existing one, this is your chance to learn from engineers who have done it, connect with the local data community, and walk away with ideas you can put to work immediately.

🎤 Session Details: Scaling to a Billion: Building a Maritime Data Lake with ClickHouse Cloud
Description: In the maritime industry, connectivity is a lifeline, powered by a complex web of satellite providers like Starlink, KVH, and OneWeb. For RUDRA, managing the massive influx of telemetry and usage data from these high-seas networks required a solution that could scale as fast as the data arrived.
This session dives into the architecture and evolution of SLASH, our specialized maritime datalake. We will share the "boots-on-the-ground" journey of adopting ClickHouse Cloud to ingest and manage over 1 billion records daily.
