pulsar

A quick queston regarding Ursa. Is it possible to run Pulsar with just:
• Brokers, Oxia, S3
• Brokers, Oxia, Hudi 
Or are the bookkeepers still required, but can be not used in some tenants ?

BookKeeper will not be a required component in Ursa. If you don't care about the low latency, the whole cluster can run only on S3

If you want to support both low latency and low costs on a single cluster. It will be configurable on the namespace level. For one namespace with low latency policy, the data will go to the bookkeeper, for one namespace low cost, the data will go to s3.

I was a bit confused, as the diagrams were pretty complex.
I was also a bit confused is it a part of Pulsar or SN offering.

I see it as a better alternative for:

and going beyond. Keeping fingers crossed for the success!
