开源云原生分布式 SQL 数据库，用 MySQL 协议同时扛事务与分析负载
面向不可预测增长的 Agent 负载设计的分布式数据库，原生支持事务、分析与向量检索，避免数据孤岛和资源争抢。
核心能力
- 用两阶段提交实现跨节点 ACID 分布式事务
- 计算与存储分离，支持不停机横向纵向扩缩容
- 内置 Raft 多副本与自动故障转移保障高可用
- TiKV 行存加 TiFlash 列存实时同步实现 HTAP
- 兼容 MySQL 8.0 协议，应用可少改或不改迁移

TiDB
TiDB (/’taɪdiːbi:/, "Ti" stands for Titanium) is an open-source, cloud-native, distributed SQL database designed for high availability, horizontal and vertical scalability, strong consistency, and high performance.
Key Features
-
Distributed Transactions: TiDB uses a two-phase commit protocol to ensure ACID compliance, providing strong consistency. Transactions span multiple nodes, and TiDB's distributed nature ensures data correctness even in the presence of network partitions or node failures.
-
Horizontal and Vertical Scalability: TiDB can be scaled horizontally by adding more nodes or vertically by increasing resources of existing nodes, all without downtime. TiDB's architecture separates computing from storage, enabling you to adjust both independently as needed for flexibility and growth.
-
High Availability: Built-in Raft consensus protocol ensures reliability and automated failover. Data is stored in multiple replicas, and transactions are committed only after writing to the majority of replicas, guaranteeing strong consistency and availability, even if some replicas fail. Geographic placement of replicas can be configured for different disaster tolerance levels.
-
Hybrid Transactional/Analytical Processing (HTAP): TiDB provides two storage engines: TiKV, a row-based storage engine, and TiFlash, a columnar storage engine. TiFlash uses the Multi-Raft Learner protocol to replicate data from TiKV in real time, ensuring consistent data between the TiKV row-based storage engine and the TiFlash columnar storage engine. The TiDB Server coordinates query execution across both TiKV and TiFlash to optimize performance.
-
Cloud-Native: TiDB can be deployed in public clouds, on-premises, or natively in Kubernetes. TiDB Operator helps manage TiDB on Kubernetes, automating cluster operations, while TiDB Cloud provides a fully-managed service for easy and economical deployment, allowing users to set up clusters with just a few clicks.
-
MySQL Compatibility: TiDB is compatible with MySQL 8.0, allowing you to use familiar protocols, frameworks and tools. You can migrate applications to TiDB without changing any code, or with minimal modifications. Additionally, TiDB provides a suite of data migration tools to help easily migrate application data into TiDB.
-
Open Source Commitment: Open source is at the core of TiDB's identity. All source code is available on GitHub under the Apache 2.0 license, including enterprise-grade features. TiDB is built with the belief that open source enables transparency, innovation, and collaboration. We actively encourage contributions from the community to help build a vibrant and inclusive ecosystem, reaffirming our commitment to open development and accessibility for everyone.
Quick Start
-
Start a TiDB cluster.
-
On local playground. To start a local test cluster, refer to the TiDB quick start guide.
-
On Kubernetes. TiDB can be easily deployed in a self-managed Kubernetes environment or Kubernetes services on public clouds using TiDB Operator. For more details, refer to the TiDB on Kubernetes quick start guide.
-
Using TiDB Cloud (recommended). TiDB Cloud offers a fully managed version of TiDB with a free plan, no credit card required, so you can get a free cluster in seconds and start easily: Sign up for TiDB Cloud.
-
-
Learn about TiDB SQL: To explore the SQL capabilities of TiDB, refer to the TiDB SQL documentation.
-
Use a MySQL driver or an ORM to Build an App with TiDB.
-
