Finalization of tablet split was only synchronizing with migrations, but that's not enough as we want to make sure that all processes like repair completes first as they might hold erm and therefore will be working with a "stale" version of token metadata. For synchronization to work properly, handling of tablet split finalize will now take over the state machine, when possible, and execute a global token metadata barrier to guarantee that update in topology by split won't cause problems. Repair for example could be writing a sstable with stale metadata, and therefore, could generate a sstable that spans multiple tablets. We don't want that to happen, therefore we need the barrier.

Scylla developer documentation
This folder contains developer-oriented documentation concerning the ScyllaDB codebase. We also have a wiki, which contains additional developer-oriented documentation. There is currently no clear definition of what goes where, so when looking for something be sure to check both.
Seastar documentation can be found here.
User documentation can be found on docs.scylladb.com
