Substrait: Cross-Language Serialization for Relational Algebra substrait.io If the title doesn’t make sense, click the page, the examples really explain it well.

I've sketched out a new specification to serialize relational algebra across systems. Builds on ideas from Apache Calcite and gaps seen in ApacheArrow and Apache Iceberg. Would love to see a community standard rise that enables algebraic microservices. substrait.io

Good progress made in the last week on type system. Up next: field references, function signatures & extension system github.com/substrait-io/s…. Share your input!

Nice to see experimentation work integrating DuckDB and substrait.io by @hfmuehleisen. github.com/duckdblabs/duc…

Check out great content this week about substrait.io by Carlo Curino at Microsoft and Ian Cook at Voltron Data linkedin.com/feed/update/ur… and youtube.com/watch?v=5JjaB7…

Check out Substrait 0.7.0, out today. Includes the support for compound extension types thanks to Jeroen at Voltron Data. github.com/substrait-io/s…

A simple way that I think about the partnership and relationship between ApacheArrow and substrait.io. Arrow provides a standardized way to move data. Substrait provides a standard way to communicate data processing instructions. (From my talk on VLDB 2025 🇬🇧)
