Introduction
TiDB is an open-source distributed relational database independently developed by PingCAP company, which supports HTAP (Hybrid Transaction and Analysis Processing), is compatible with MySQL protocol and ecosystem, and has core capabilities such as financial grade high availability, horizontal elastic scaling, and real-time OLAP analysis.
Applicable Scene
Suitable for high consistency and high availability scenarios in the financial industry, massive data high concurrency OLTP scenarios, and HTAP mixed load scenarios that require real-time data analysis.
Pros: TiDB has financial grade high availability (RTO ≤ 30s, RPO=0), unlimited horizontal scalability (supporting PB level data and 512 node clusters), real-time HTAP integrated architecture (row storage TiKV processing OLTP+column storage TiFlash acceleration OLAP), and is compatible with MySQL protocol and ecosystem, significantly reducing migration and operation costs.
Cons: TiDB has incomplete support for complex SQL (such as some stored procedures and GIS functions), higher cross node transaction latency than standalone MySQL, and a distributed architecture requires higher hardware configuration (such as NVMe SSD, multi-core CPU), resulting in higher initial resource investment and operational complexity.
