分布式交易密钥值数据库,最初是用来补充TiDB的

Website QQ Documents QQ社区聊天TiKV是一个开源,发行,和交易密钥值数据库. 与其他传统的NoSQL系统不同,TiKV不仅提供古典密钥值API,还提供交易性ACID达标的API. TiKV由Rust建造,由Raft提供动力,最初由PingCAP创建以补充TiDB,这是一个可兼容MySQL协议的分布式HTAP数据库. TiKV("Ti'代表钛")的设计灵感来源于Google的一些巨大的分布式系统,如BigTable,斯潘纳和Percolator等,以及近年来学术界的一些最新成就,如Raft共识算法. 如果你有兴趣为TiKV做贡献,或者想从源头建起,请参见Conformation.md. 关于面向维护的代码读取和审查上下文,参见Doc/维护-guides/README.md. TiKV是C的一个毕业项目..

核心特点

•Geo-Replication
•Horizontal scalability
•Consistent distributed transactions
•Coprocessor support
•Cooperates with TiDB
•Placement Driver: PD is the cluster manager of TiKV, which periodically checks replication constraints to balance load and data automatically.
•Store: There is a RocksDB within each Store and it stores data into the local disk.
•Region: Region is the basic unit of Key-Value data movement. Each Region is replicated to multiple Nodes. These multiple replicas form a Raft group.
•Node: A physical node in the cluster. Within each node, there are one or more Stores. Within each Store, there are many Regions.
•PD endpoints: 127.0.0.1:23791, 127.0.0.1:23792, 127.0.0.1:23793
