File generation is slow

[fenollp]

Hi!

I'm generating *.validate.rs files with buf with

  - local: protoc-gen-prost-validate
    out: generated/rust/src/grpc
    strategy: all
    opt:
      - enable_type_names

and

buf generate --timeout 0
however this usually takes 5-7 minutes. I'd rather it took a few seconds tops.

Any ideas where the slowness could be and what could be done about it? I'll gladly help :)

Note:

• I have 503 .proto files
• defining 8428 messages and 1828 enums
• and 5367 validation annotations

Hey @Adphi, I hope all is well with you.
Any clue on where to dig on this / what to probably parallelize?
Thanks

Hi @fenollp,

Sorry for the delay.
Adding some logging to protoc-gen-prost-validate could help, for example to confirm that messages aren’t being generated more than once.
