TiKV
A distributed transactional key-value database. Based on the design of Google Spanner and HBase, but simpler to manage and without dependencies on any distributed filesystem
Geo-replication
TiKV uses the Raft consensus algorithm and the Placement Driver to support geo-replication.
Horizontal scalability
With the Placement Driver and carefully designed Raft groups, TiKV excels in horizontal scalability and can easily scale to 100+ terabytes of data.
Consistent distributed transactions
Similar to Google’s Spanner, TiKV supports externally consistent distributed transactions.
Coprocessor support
Similar to Hbase, TiKV implements a coprocessor framework to support distributed computing.
