TiDB HTAP

TiDB is an open-source, distributed relational database supporting both OLTP (Online Transaction Processing) and OLAP (Online Analytical Processing) workloads. It uses a distributed, shared-nothing architecture with three layers: TiDB (stateless SQL layer), TiKV (distributed key-value storage), and PD (distributed consensus and scheduling). TiDB enables real-time analytics on transactional data without ETL. It's particularly popular in fintech and e-commerce where analytical insights on live data are valuable. TiDB Cloud is the managed offering.
