Clarify storage and distribution APIs

[fizx]

According to the marketing page, there are storage integrations with tencent cloud, but they don't appear to exist in the source code.

1. How do you plan on persisting indexes between pod restarts?
2. Can there be more than one index per cluster?
3. Can indexes be written and read from in an online manner?

nothing is bind to tencent cloud. you have the full autonomy to use whatever cloud service

1. yes and that's actually the orchestration's work, e.g. docker swarm, kubernetes
2. yes, we call it shards, supported already
3. not really, as that requires every indexer to support RW at the same time. or we add a buffer to generally enable that. still in plan.

document and tutorial are still in build, please be patient.

Please don't quickly close tickets, as the further discussion might be interesting, and you might find capable people willing to help out on the project. I'm not intending to criticize your work, instead I find it compelling enough to want to work with you to build it.

For example, I have experience building the type of buffer you talk about and would be interested in contributing an implementation.
