Databases at tech events
26 write-ups · 15 events · 2024–2026
This hub gathers talks and demos on databases: PostgreSQL, ClickHouse, CockroachDB, MotherDuck and more. The meetups I attend keep returning to analytics at speed, distributed SQL resilience, running databases in cloud native environments, and how data stores connect to AI workloads. I keep these notes for anyone choosing a data store.
