Before you can contribute code to Scylla for the first time, you should sign the Contributor License Agreement and send the signed form [email protected]. You can then submit your changes as patches to the to the scylladb-dev mailing list or as a pull request to the Scylla project on github. If you need help formatting or sending patches, check out these instructions.
The Scylla C++ source code uses the Seastar coding style so please adhere to that in your patches. Note that Scylla code is written with using namespace seastar, so should not explicitly add the seastar:: prefix to Seastar symbols. You will usually not need to add using namespace seastar to new source files, because most Scylla header files have #include "seastarx.hh", which does this.
