TiDB is an open source distributed scalable hybrid transactional and analytical processing (HTAP) database built by PingCAP.
In the current database landscape, infrastructure engineers often have to use one database for online transactional processing (OLTP) and another for online analytical processing (OLAP). Seeing no good solution that can do both in real-time, PingCAP cofounders decided to build a globally scalable Hybrid Transactional/Analytical Processing (HTAP) database the open-source way.
Now, a new storage component that’s columnar-based, called TiFlash (currently in beta) is being introduced, that sits alongside TiKV.
|Typical application scenarios|
TiDB is designed to support both OLTP and OLAP scenarios. You can use TiDB, the stateless SQL layer compatible with MySQL, for OLTP and ad-hoc OLAP workload, and TiSpark, the TiDB connector for Spark, to process complex OLAP queries.
|Licensing and pricing models|
Open Source Apache 2.0 with either commercial licensing or fully-hosted DB-as-a-service subscription model.
