Commit f2ff701489 introduced
a yield in update_effective_replication_map that might
cause the storage_group manager to be inconsistent with the
new effective_replication_map (e.g. if yielding right
before calling `handle_tablet_split_completion`.
Also, yielding inside storage_service::replicate_to_all_cores
update loop means that base tables and their views
aren't updated atomically, that caused scylladb/scylladb#17786
This change essentially reverts f2ff701489
and makes handle_tablet_split_completion synchronous too.
The stopped compaction groups future is kept as a member and
storage_group_manager::stop() consumes this future during table::stop().
- storage_service: replicate_to_all_cores: update base and view tables atomically
Currently, the loop updating all tables (including views) with the
new effective_replication_map may yield, and therefore expose
a state where the base and view tables effective_replication_map
and topology are out of sync (as seen in scylladb/scylladb#17786)
To prevent that, loop over all base tables and for each table
update the base table and all views atomically, without yielding,
and so allow yielding only between base tables.
* Regression was introduced in f2ff701489, so backport is required to 6.x, 2024.2
