Seastar is an advanced, open-source C++ framework for high-performance server applications on modern hardware. Seastar is used in Scylla, a high-performance NoSQL database compatible with Apache Cassandra Ceph community is currently working on migration to this project as well. Hence it makes much sense (especially for SUSE SES team) to start gaining experience in using it. Getting familiar with advanced C++ features like "futures" would be nice too.
