Feldera

Feldera is the world's first "incremental" compute engine that can maintain *any* SQL incrementally - even for deeply nested views with hundreds of joins, distincts, window functions, aggregates, unions and even recursion. No full recomputes like with a batch engine. Just instant updates to the parts of your SQL views that changed. Enterprises are migrating hundreds of thousands of lines of SQL from their warehouses to Feldera and seeing sub-second updates in real time, with up to 95% lower cloud spend.
