How Good is TiDB as an HTAP System? A HATtrick Benchmark
Inspired by the SIGMOD/PODS 22 paper “How Good is my #HTAP System” and HATtrick, the proposed benchmark tool, we tested the TP/AP performance isolation and horizontal scalability of TiDB as an HTAP database.
Speeding up a SaaS Platform by 5x in a Day without Changing the Code
In this article, we compare the performance of TiDB and MySQL on one of the most popular low-code SaaS platforms, Corteza CRM. We also demonstrate how TiDB leverages its HTAP capabilities to the SaaS platform without any code changes and speeds up development of new applications.
Improve Performance and Data Availability with Elastic Block Store
In this blog, we will explain that with careful selection of Elastic Block Store (EBS) types and clever optimizations, deploying DBaaS on EBS can achieve even better performance than on local disks.
