Some basic facts about TiKV
The Ti in TiKV stands for titanium. Titanium has the highest strength-to-density ratio of any metallic element and is named after the Titans of Greek mythology.
|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.|
The basic architecture of TiKV is described in the diagram below:
