StarRocks is backed by StarRocks.Inc, a global company based in the US and China. We developed StarRocks in early 2020 based on version 0.13 of Apache Doris (incubating).
Due to the different vision, StarRocks took a different development path. We are very grateful to the Apache Doris community for contributing such a great OLAP database.
We have adopted the framework and columnar storage engine from Apache Doris (incubating) while adding a full vector execution engine, CBO optimizer, real-time update engine and other important features. By September 2021, over 60% of StarRocks' code is added or modified compared to Apache Doris (incubating). For more information about our work, please refer to here.
StarRocks is a source available software licensed under Elastic License 2.0. With the open core model, we want to give both enterprise users and individual developers equal and complete access to the core features we are proud of, while giving the company more resources to ensure continuous innovation.
The adoption of Elastic License 2.0 has virtually no impact on the vast majority of the community. Similar agreements are already widely used, including Elastic Stack, Confluent, Redis Modules and so on. We have found a way to balance open source code and commercial development. In the future, we will work actively with cloud vendors to provide better products and services to our users. For more details on the Elastic License 2.0, please see here.
