I share my reaction to composable data sources, one of the biggest features celebrated at Tableau Conference 2026. While I think it's a genuinely major innovation, I point out that Tableau first talked about it back in 2024 and it still hasn't shipped, which raises concerns about their pace of delivery.

## Key takeaways

- Composable data sources were one of the headline features celebrated at Tableau Conference 2026, with potential to reshape the ecosystem
- Tableau first discussed this feature in 2024, yet two years on it still hasn't shipped and may only appear in an upcoming beta
- Competitors like Hex, Sigma, Omni and Golden have shipped much of the idealised AI-driven experience in a fraction of the time, raising questions about Tableau's shipping cadence
