You can see this manual of production-like cluster deployment presented by Build from source get( b'foo')) # b'baz' Deploy a cluster with TiUP TiKV is able to run separately with PD, which is the minimal deployment required.įrom tikv_client import RawClient client = RawClient. You can see this page for a step by step tutorial. The most quickest to try out TiKV with TiDB is using TiUP, a component manager for TiDB. Quick start Deploy a playground with TiUP The status of each Region and Store is reported to PD regularly. When a node starts, the metadata of the Node, Store and Region are recorded into PD. Within each Store, there are many Regions. Within each node, there are one or more Stores. These multiple replicas form a Raft group. Each Region is replicated to multiple Nodes. Region: Region is the basic unit of Key-Value data movement.Store: There is a RocksDB within each Store and it stores data into the local disk.Placement Driver: PD is the cluster manager of TiKV, which periodically checks replication constraints to balance load and data automatically.If you have any suggestions or issues regarding documentation, offer your feedback here. We have migrated our documentation from the TiKV's wiki page to the official website. For more details on concepts and designs behind TiKV, see Deep Dive TiKV. Thanks to the internal optimization, TiKV and TiDB can work together to be a compelling database solution with high horizontal scalability, externally-consistent transactions, support for RDBMS, and NoSQL design patterns.įor instructions on deployment, configuration, and maintenance of TiKV,see TiKV documentation on our website. Similar to HBase, TiKV implements a coprocessor framework to support distributed computing. Similar to Google's Spanner, TiKV supports externally-consistent distributed transactions. With PD and carefully designed Raft groups, TiKV excels in horizontal scalability and can easily scale to 100+ TBs of data. TiKV uses Raft and the Placement Driver to support Geo-Replication. FOR UPDATE), and externally consistent reads and writes in distributed transactions. TiKV also provides snapshot isolation (SI), snapshot isolation with lock (SQL: SELECT. The transaction model is similar to Google's Percolator with some performance improvements. Placement Driver (PD), which is introduced to implement auto-sharding, enables automatic data migration. With the implementation of the Raft consensus algorithm in Rust and consensus state stored in RocksDB, TiKV guarantees data consistency. For details about who's involved and how TiKV plays a role, read the CNCF announcement. If you are an organization that wants to help shape the evolution of technologies that are container-packaged, dynamically-scheduled and microservices-oriented, consider joining the CNCF. TiKV is a graduated project of the Cloud Native Computing Foundation (CNCF). If you're interested in contributing to TiKV, or want to build it from source, see CONTRIBUTING.md. The design of TiKV ('Ti' stands for titanium) is inspired by some great distributed systems from Google, such as BigTable, Spanner, and Percolator, and some of the latest achievements in academia in recent years, such as the Raft consensus algorithm. Built in Rust and powered by Raft, TiKV was originally created by PingCAP to complement TiDB, a distributed HTAP database compatible with the MySQL protocol. Unlike other traditional NoSQL systems, TiKV not only provides classical key-value APIs, but also transactional APIs with ACID compliance. TiKV is an open-source, distributed, and transactional key-value database.
