OpenIVM: refresh the changes, not the whole pipeline

Editorial interest 78/100 Selection signal · not a rating of the site

OpenIVM is an open-source compiler that turns SQL materialized views into incremental SQL for DuckDB and, in development, Spark.

Landing page captured for the 2026-09-30 issue.

For: DuckDB users and data-pipeline builders
Worth noticing: Changes are represented as signed tuples (+1 or −1); the page says unsupported views are classified for full refresh up front.

Field notes

The page describes delta rules derived from operator algebra rather than pattern matching, and says a view is either maintained exactly or classified up front for full refresh. It places view and auxiliary state in ordinary tables, including for batch tables, and links to a SIGMOD Companion 2024 paper. Spark support and the benchmark display are marked as in development or coming soon, so those parts are not presented as ready.
