NewSQL, HTAP: TiDB

a very informative podcast interview


TiDB: Distributed NewSQL with Kevin Xu - Software Engineering Daily

"TiDB is an open source database built on RocksDB and Kubernetes. TiDB is widely used in China by high volume applications such as bike sharing and massively multiplayer online games. Kevin Xu works at PingCAP, a company built around TiDB. He joins the show to talk about modern databases, distributed systems, and the architecture for TiDB."

Inspired by Google Spanner paper

pingcap/tidb: TiDB is a distributed HTAP database compatible with the MySQL protocol

"TiDB (The pronunciation is: /'taɪdiːbi:/ tai-D-B, etymology: titanium) is an open-source distributed scalable Hybrid Transactional and Analytical Processing (HTAP) database. It features horizontal scalability, strong consistency, and high availability.
TiDB is MySQL compatible and serves as a one-stop data warehouse for both OLTP (Online Transactional Processing) and OLAP (Online Analytical Processing) workloads."

in GoLang :)

NewSQL : HTAP = OLTP + OLAP 

Citus what is it good for? OLTP? OLAP? HTAP?

"Hybrid transaction/analytical processing (HTAP) is an emerging application architecture that “breaks the wall” between transaction processing and analytics. It enables more informed and “in business real time” decision making."
