photo by Adrian I gave a talk at Monitorama in Portland Oregon in June, which set out the idea that carbon is just another metric to monitor, and that in a few years most of the monitoring and performance tuning tools are going to be reporting and optimizing for carbon alongside latency, throughput, availability and cost.

A Cassandra database cluster had switched to Ubuntu and noticed write latency increased by over 30%. The change was obvious in the production graphs, showing a drop in write latencies: Once tested more broadly, it showed the write latencies dropped by 43%, delivering slightly better performance than on CentOS.

I previously wrote about Netflix in [2015] and [2016], and if you are interested in what it's like to work here, I already covered much in those posts. A latency outlier issue that happened every 15 minutes. I've now worked at Netflix for over three years. Time flies! Java core dump analysis for a crashing JVM. -

In 2010, however, nearly none of it existed: the CNCF wasn’t formed until 2015! There is a downside to fetching this data on-demand: this adds latency to the first request to a cluster. This is the first in a series of posts on our journey to service mesh, so stay tuned. It’s been a great experience working with you all on this.

Passive instances across regions are also possible, though it is recommended to operate in the same region as the database host in order to keep the change capture latencies low. Stay Tuned DBLog has additional capabilities which are not covered by this blog post, such as: Ability to capture table schemas without using locks.
