StarRocks

StarRocks is a vectorised SQL analytics engine. It supports real-time updates through primary keys and can query lakehouse data directly in Hive, Iceberg, Delta Lake and Hudi formats. It is a Linux Foundation project, and its source code is licensed under Apache-2.0, so it is open source and free to use. StarRocks is run self-managed. No commercial or managed edition was verified, so buyers who want a vendor-backed service should confirm whether one exists and what it costs. The latest release is 4.1.3, dated 17 September 2026. This release changes how VARCHAR types are handled in CREATE TABLE AS SELECT statements, so teams that create tables this way should test the behaviour before upgrading, since existing statements may produce different column definitions. Because the engine can query tables in place across several lakehouse formats, it is relevant to teams that want analytical SQL over data held in object storage, as well as those that load data into the engine itself. No licence change, closed product line or dormant status was found, and the project is active with a recent release.
