Arrow Flight SQL in KurrentDB v26.1 Part 1 (Full Video) | Kurrent Konversations
Conversation between Tony Young & Stephen Tung recorded May 15th 2026.
Traditionally, querying event-sourced data meant writing custom code, managing complex projections, or dealing with the dreaded "dual-write" problem. Not anymore.
In this session, Stephen Tung (Developer Advocate) and Tony Young (Principal Solutions Architect) introduce Kurrent v26.1 and explain how the inclusion of Arrow Flight SQL completely collapses your time to insight. Learn how to connect your favorite SQL tools directly to your event-native database without giving up any temporal or causal context.
