Vasto

Allows growing or shrinking the cluster without service interruption, using efficient data migration via SSTable writes and jumping consistent hashing for minimal data movement.

Managed via simple commands for creating, deleting, and resizing keyspaces, abstracting away the complexity of partitioning and replication as highlighted in the philosophy.

Uses a single master without gossip protocols or consensus algorithms, enabling fast setup and failure detection with soft state recovery on restart.

Supports reads and writes on all replicas with changes propagated within milliseconds, and conflict resolution based on event timestamps for distributed environments.
