TiDB Weekly

News & blog posts

High read latency and network traffic are common issues for a multi-region architecture. At TiDB Hackathon 2019, a team won 2nd place by reducing multi-region read latency and network traffic by 50%.

Last week, we published a post that introduces how the team reduced the read latency and network traffic by half for a multi-region architecture. If you have similar problems, we hope this post will help you.

How We Reduced Multi-region Read Latency and Network Traffic by 50%

Last week, we also published the third (and last, for now) post in a series on remote work by Nick Cameron. This post talks a bit about some of the practicalities, specifically around work/life balance.
