The goal of the server license is to require that enhancements to Scylla be released to the community. Traditional GPL often does not achieve this anymore as a huge amount of software runs in the cloud. For example, Google has no obligation to release their improvements to the MySQL kernel – if they do, they are being nice.
We promise that we will not seek to enforce the copyleft provisions in the AGPL v3.0 against you if your application (a) does not link to the Scylla database directly but exclusively uses Scylla drivers, and (b) you have not modified, added to, or adapted the source code of the Scylla database in a way that would result in the creation of a “modified version” of or a “work based on” the Scylla database as such terms are used in the AGPL v3.0. Scylla works with unmodified Apache Cassandra drivers (the part you link with your application), which are released under the Apache license, which is copyleft free.
If the above is not enough to satisfy your organization’s vast legal department (some will not approve GPL in any form), commercial licenses are available. Feel free to contact us for details.
