Sorry to weigh in at the last minute, but I'm wary of gRPC over just JSON, so -1 to that specific choice. Everything else I'm happy with.

I (or Andrew G) will follow up with more details shortly.

ah, good call.

I guess the email template can be updated:

Only votes from PMC members are binding, but members of the community are encouraged to check the AIP and vote with "(non-binding)".


+1 (binding)

Thanks,

Ping

Thank you . And BTW. It's binding Ping :). For AIP's commiter's votes are binding. See <https://github.com/apache/airflow/blob/main/CONTRIBUTING.rst#commit-policy> :D

Hey everyone,

Just a summary of where we are:

It's been long in the making, but I think it might be a great step-forward to our long-term multi-tenancy goal. I believe the proposal I have is quite well thought out and discussed a lot in the past:

* we have a working POC for implementation used for performance testing: <https://github.com/apache/airflow/pull/25094> * it is based on on industry-standard open-source gRPC (which is already our dependency) which fits better the RPC "model" we need than our public REST API. * it has moderate performance impact and rather good maintainability features (very little impact on regular development effort) * it is fully backwards compatible - the new DB isolation will be an optional feature
* has a solid plan for full test coverage in our CI
* has a backing and plans for more extensive complete testing in "real" environment with Google Composer team support * allows for further extensions as part of AIP-1 (I am planning to re-establish sig-multitenancy effort for follow up AIPs once this one is well in progress).


J.
