Vanguard 2017 roadmap

This initial release of Siren Vanguard includes an implementation of the original Siren Join algorithm, but in general it provides better performance and caching than Siren Join in many scenarios. The next release of Vanguard will include a fully distributed join algorithm that will enable horizontal scaling. We will also release a comprehensive set of benchmarks to demonstrate its scalability.


Vanguard is free to use also for commercial purposes for up to one data node in your Elasticsearch installation.

For cluster deployment, a commercial licence is required, priced per node.
