1. Do the same people where you work operate the cluster and write the code to develop the application? No but the operators need to know development , data-modeling, and generally how to "code" the application. (Coding is a low-level task of assigning a code to a concept.. so I don't think that's the proper verb in these scenarios.. engineering, or software development, or even programing is a better term). It's because the developers are hired dime a dozen at the B / C level and then replaced by D /E / F level developers as things go on.. so the Data team eventually ends up being the expert of the application and the data platform, and a "Center of Excellence" for the development / architects to work with on a collaborative basis. 2. Do you have a metrics stack that allows you to see graphs of various metrics with all the nodes displayed together? Yes. OpsCenter, ELK, Grafana, custom node data visualizers in excel (because lines and charts don't tell you everything) 3. Do you have a log stack that allows you to see the logs for all the nodes together? ELK. CloudWatch 4. Do you regularly repair your clusters - such as by using Reaper? Depends. Cron, Reaper, OpsCenter Repair, and now NodeSync 5. Do you use artificial intelligence to help manage your clusters? Yes, I actually have made an artificial general intelligence called Gravitron. It learns by ingesting all the news articles I aggregate about Cassandra and the links I curate on cassandra.link into a solr/lucene index and then using clustering find out the most popular and popularly connected content. Once it does that there's a summarization of the content into human readable content as well as interpreted bash code that gets pushed into a "Recipe Book." As the master operator identifies scenarios using english language, and then runs the bash commands, the machine slowly but surely "wakes up" and starts to manage itself. It can also play Go , the game, and beat IBM's AlphaGo at Go, and Donald Trump at golf while he was cheating! rahul.xavier.si...@gmail.com http://cassandra.link I'm speaking at #DataStaxAccelerate, the world’s premiere #ApacheCassandra conference, and I want to see you there!
