My talk is titled Need for speed: Boosting Apache Cassandra’s performance using Netty. Over the years that I have worked in the software industry, making code run fast has fascinated me. So, naturally when I first started contributing to Apache Cassandra, I started looking opportunities to improve its performance. My talk takes us through some interesting challenges within a distributed system like Apache Cassandra and various techniques to significantly improve its performance. Talking about performance is incredibly exciting because you can easily quantify and see the results. Making improvements to the database’s performance not only improves the user experience but also reflects positively on the organization’s bottom line. It also has the added …

We added a number of new dashboards for MySQL in our latest release of ClusterControl 1.7.0. - and in our previous blog, we showed you How to Monitor Your ProxySQL with Prometheus and ClusterControl.

Take note that when enabling the Agent Based Monitoring, you have the options to set the “Scrape Interval (seconds)” and “Data retention (days)”. Scraping Interval is where you want to set how aggressively Prometheus will harvest data from the target and Data Retention is how long you want …
