The WASM UDF implementation has changed since the last time the docs were written. In particular, the Rust helper library has been released, and using it should be the recommended method. Some decisions that were only experimental at the start, were also "set in stone", so we should refer to them as such. The docs also contain some code examples. This patch adds tests for these examples to make sure that they are not wrong and misleading. Closes #12941
Scylla developer documentation
This folder contains developer-oriented documentation concerning the ScyllaDB codebase. We also have a wiki, which contains additional developer-oriented documentation. There is currently no clear definition of what goes where, so when looking for something be sure to check both.
Seastar documentation can be found here.
User documentation can be found on docs.scylladb.com
For information on how to build Scylla and how to contribute visit HACKING.md and CONTRIBUTING.md.
