什麽是TiDB?

TiDB(發音是:/'taɪdiːbi:/tai-D-B,詞源:titanium)是一個混郃交易/分析処理(HTAP)數據庫。受Google F1和Google Spanner設計的啓發,TiDB具有無限的橫曏擴展性,強大的一致性和高可用性。 TiDB的目標是作爲在線交易和分析的一站式解決方案。

  • 水平可伸縮性
隨著業務的增長,增加TiDB。衹需添加更多機器,您就可以增加存儲和計算的容量。

  • 與MySQL協議兼容

使用TiDB作爲MySQL。在大多數情況下,您可以使用TiDB替換MySQL來爲應用程序提供動力,而無需更改任何代碼行。

  • 自動故障轉移和高可用性
您的數據和應用程序始終処於開啓狀態。 TiDB可自動処理故障,竝保護您的應用程序免受機器故障甚至整個數據中心的停機。

  • 一致的分佈式交易

將TiDB眡爲一台單機RDBMS。您可以開始跨越多台機器的交易,而不必擔心一致性問題。 TiDB使您的應用程序代碼簡單而強大。

  • 在線DDL
根據您的需求變化縯變TiDB模式。您可以添加新的列和索引,而無需停止或影響正在進行的操作。

  • 支持多種存儲引擎
給你最喜歡的引擎加電TiDB。 TiDB支持本地存儲引擎,如GolevelDB和BoltDB,以及分佈式存儲引擎 TiKV

What is TiDB?

TiDB ("Ti" stands for Titanium) is an open-source NewSQL database that supports Hybrid Transactional and Analytical Processing (HTAP) workloads. It is MySQL compatible and features horizontal scalability, strong consistency, and high availability.

  • Horizontal Scalability

    TiDB expands both SQL processing and storage by simply adding new nodes. This makes infrastructure capacity planning both easier and more cost-effective than traditional relational databases which only scale vertically.

  • MySQL Compatible Syntax

    TiDB acts like it is a MySQL 5.7 server to your applications. You can continue to use all of the existing MySQL client libraries, and in many cases, you will not need to change a single line of code in your application. Because TiDB is built from scratch, not a MySQL fork, please check out the list of known compatibility differences.

  • Distributed Transactions with Strong Consistency

    TiDB internally shards table into small range-based chunks that we refer to as "regions". Each region defaults to approximately 100MiB in size, and TiDB uses a Two-phase commit internally to ensure that regions are maintained in a transactionally consistent way.

  • Cloud Native

    TiDB is designed to work in the cloud -- public, private, or hybrid -- making deployment, provisioning, operations, and maintenance simple.

    The storage layer of TiDB, called TiKV, became a Cloud Native Computing Foundation member project in 2018. The architecture of the TiDB platform also allows SQL processing and storage to be scaled independently of each other in a very cloud-friendly manner.

  • Minimize ETL

    TiDB is designed to support both transaction processing (OLTP) and analytical processing (OLAP) workloads. This means that while you may have traditionally transacted on MySQL and then Extracted, Transformed and Loaded (ETL) data into a column store for analytical processing, this step is no longer required.

  • High Availability

    TiDB uses the Raft consensus algorithm to ensure that data is highly available and safely replicated throughout storage in Raft groups. In the event of failure, a Raft group will automatically elect a new leader for the failed member, and self-heal the TiDB cluster without any required manual intervention. Failure and self-healing operations are also transparent to applications.
