Serverless support for version 4.x
Enables basic support for serverless Scylla clusters. Changes include:
- Necessary core code changes
- Slight changes to test utilities and new tests
- Removal of code parts related to Datastax Astra
Tested with both remote clusters and CCM with SNI proxy locally.
This error in integration tests looks a bit worrying:

Note, we should adopt a waterfall procedure. First apply fixes/features on the main branch, then selectively backport to branches.
Starting with the older branch means that there is a window where someone can upgrade from an older branch with the fix/feature, to a newer branch without the fix/feature and be exposed to a regression.

The situation is a bit different in Java Driver. We essentially have two “master”s - scylla-3.x and scylla-4.x, as those are essentially two different drivers not sharing much of the codebase.
The older branches in this repo are branches like scylla-3.7.2.x and we very rarely backport there.
I should better document this organization and clean up unrelated branches (remnants of upstream Datastax repo)
Closing. In case the topic of serverless returns, the code can be checked out at 4.x-serverless-feature
