Abstract
Replication is improved in a globally distributed database, such as a replicated sharded database, which uses raft-based asynchronous database replication. Improvements include Raft log persistence, coordination of followers' processing speed, transaction outcome determination, and column name compression, and improved failover time through heartbeat consolidation and keeping apply processes of followers running across failovers.
