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. As before, no one at Netflix has asked me to write this, and this is my personal blog and not a company post. A latency outlier issue that happened every 15 minutes. Time flies!

Requirements In a previous blog post, we discussed Delta , a data enrichment and synchronization platform. In our Delta blog post , we also described use cases beyond data synchronization, such as event processing. Supports any kind of output , so that the output can be a stream, datastore, or even an API. Figure 4— Delta Connector.

You may have read some blog posts or heard conference talks on this topic and think you know the answers. One question I’ve often encountered is, “Why do we need HTTP/3 so soon after HTTP/2, which was only standardized in 2015?” Stay tuned!
