It seems like portions of what you discussed would probably be nominally
impacted by indexes while other would be very impacted. Also seems like
compound-qualifier indexing would potentially be of i
One sparse use case for us is rate limit detection. We store user events
in an Event table whose primary key is a unique timestamp (sharded to avoid

Can you expound on use cases? The pros and cons
Can indexing be boiled down to these questions to start?
1) Per-region or Per-table
2) Sync or Async
3) Client-managed or Server-managed
4) Schema or Schema-less
Definitions:
1)
- Per-region: the index entries are stored on the same machine as the
primary rows
- Per-table: each index is stored i

Let me know.
I won't have time to prepare much for this, though. So it would be an ad hoc
discussion, maybe with some white boarding.
