SCILLADB developers have recently announced their decision to transfer the project to a proprietary license, limiting its scope. The branch scylladb 6.2.x will be the last available under the AGPL license. Interested parties who wish to continue developing Scylladb under the old license can create a fork of the project.
Prior to this change, the SCILLADB project followed the Open Core development model, where the base part of the product was developed under a free license, while expanded functionality was only available to owners of a commercial license. With the new licensing scheme, the open editorial office of SCILLADB OSS will no longer be published, and the previously closed commercial product SCYLLADB ENTERPRISE will be distributed with the source code under a proprietary license. Users will now have access to the full version of SCYLLADB ENTERPRISE for free under certain conditions.
The new license restricts the use of SCILLADB for competition with developers’ products and services, as well as for creating SAAS and DBAAS. It does not limit the use of the free product for commercial purposes or in a working environment, as long as the total storage size on all cluster components does not exceed 10TB, and no more than 50 VCPU are used for data processing. Users who do not meet these criteria are encouraged to purchase a commercial license.
For instance, users can utilize SCYLLADB for free on a three-node cluster, each with 16 logical CPUs and a 3TB disk repository. This configuration can handle 100-200 thousand operations per second. Distribution of SCYLLADB and modifications to the code are allowed under the same license, provided that all changes are documented along with information about the original author.
