Conference organizers for The ASF are pleased to announce the Call for Presentations for two events coming in October. This year, Community Over Code Glasgow will feature a co-located, standalone, all-day conference: Lakehouse Day EU 2026.
Lakehouse Day will provide a place for the projects in and around the lakehouse ecosystem to network, connect, and drive innovation across the space. With multiple tracks and a full day of programming, the event creates a focused space for deep technical discussion, real-world use cases, and cross-project collaboration.
Alongside this new addition, Community Over Code Glasgow continues The ASF event tradition of spotlighting the people, projects, and practices that power open source. The Calls for Presentations for both events are now open, inviting the ASF community and open source practitioners from around the world to share their ideas, experiences, and insights.
Proposal submissions for Community Over Code Glasgow and Lakehouse Day EU 2026 are open until 23:59 UTC on March 20, 2026.
