Donating proto/grpc schema registry

[Alex Van Boxel]

Hi all,

we've build a gRPC schema registry and want to see if other people are interested in this: 

https://github.com/anemos-io/metastore/

I know that most people just use git as a registry, and that's ok but I believe having a registry spec (and an implantation) can help the community in the following domains:

• having a defined gRPC schema API can help to have a common way to talk to gRPC/Proto registries. This can combat fragmentation on the API level
• having an API can help as a store from dynamically created descriptors. Example: we have a tool that data governance can use to define business contracts, the tool uses the API to interact. verify and store the descriptors.
• having a spec can help data (I live mainly in the data space, sorry) systems (like Kafka or Apache Beam) to get up-to-date descriptors for their data workload.

So I like to donate a proposal of grpc.registry.v1alpha1, as it is now. From there on interested people can start discussing.

The repo contains a working implementation of the spec that we're using. For us, it's the centrepiece of our big data solution. I would like to donate this to the gRPC ecosystem. It's been proven very useful, for the following features:

• Dynamic descriptors (created by tools) can be visualized in git (super traceability)
• pluggable backend gcs, file and memory (we're using Google Cloud Storage)
• Notification of changes (pluggable), we're using PubSub to restart our pipelines when descriptors changed
• our data pipelines talk to the registry to get up-to-data contracts
• our gRPC ingestion API's are generated on the fly (they use the proto-java implementation to make dynamic services)

OK, I've talked a lot of Big Data use cases but I'm sure API use cases are to be found as well.

As a reference, my slides of the gRPC conf talk of last year:

• https://docs.google.com/presentation/d/1l3TqwD0pR8-qJ3IOL6fRSjcXpoMqbvcFfgLGv3Shi2E/edit?usp=sharing

So, is this something that is interesting to the community on who can help me getting this integrated?

not directly related, but is there some place where I can access the gRPC conf videos / slides?

thanks
