UDFs in Wasm vs Lua

Hi everyone! I’m experimenting with scylla UDFs and was wondering if there are any benchmarks on running udfs based on wasm (rust-based using the helper library) vs Lua.

Is any language more “stable” in any way? It seems that Lua support exists for quite a while now and wasm is more recent.


I am not aware of any benchmarks we have done to compare the two.

Lua UDFs indeed exist for quite a while, while WASM is a more recent addition. That said, WASM is much more actively developed as we believe it is a much more flexible and performant platform for UDFs, than Lua is.
