Cassandra video tutorials for administrators.

[ju...@biblicaltext.com]

I know there is a lot of useful information out there, including on you tube. I am looking for recommendations for good introductory (but detailed) videos created by people who have cassandra cluster management, that outline all the day to day activities someone who is managing a cluster would understand and/or be doing.

I believe I have a reasonably good grasp of Cassandra, but I am in that “I don’t know what I don’t know phase” where there might be things that I am unaware I should understand.

Thanks,
Justine

+1 for data modeling. If an admin can spend the day helping app teams get the model right BEFORE hitting production, those are the best days (and prevent the bad days of trying to engineer around a bad model/migrate data to new tables/etc)

I also find good value in understanding the availability guarantees of Cassandra and the underlying VMs/hardware for each application. However, app teams do not usually spend the necessary time to understand how to construct their connections to take full advantage of the powerful cluster they have. Learning about the connection policies of the various drivers is important. Then “encourage” the app team to actually test their availability in lower life cycles by simulating various failure scenarios.

Then there is monitoring – a beast of a subject… Trying to figure out what is actionable is a life-long journey. 😉

Fortunately, my “How to Become the Lord of the Rings” talk from Cassandra Summit 2019 is not available. You can avoid my ugly mug.

Hi Justine,

Welcome to the community! There is quite an extensive playlist here from an older DataStax Academy course on Cassandra admin: https://www.youtube.com/playlist?list=PL2g2h-wyI4SrHMlHBJVe_or_Ryek2THgQ [youtube.com]<https://urldefense.com/v3/__https:/www.youtube.com/playlist?list=PL2g2h-wyI4SrHMlHBJVe_or_Ryek2THgQ__;!!M-nmYVHPHQ!Y4hNxlUvhogHuTml9mLOFyubScjVzEeV9bplBPj_Hml9usrybcMGsXFQPiisBMCZR4XBy2E$>

An exact daily task list type video I haven't seen. In my experience the fundamental things to know for the day to day ops are running repairs and backups. More one off but useful topics are things like adding or removing nodes from the cluster or even restoring a backup. To be helpful with developers using the system, it's good to get a foundation in data modeling. You'll find that a lot of issues come down to just a bad data model and knowing what that looks like can save a lot of time. Here's a playlist for that: https://www.youtube.com/playlist?list=PL2g2h-wyI4SqIigskyJNAeL2vSTJZU_Qp [youtube.com]<https://urldefense.com/v3/__https:/www.youtube.com/playlist?list=PL2g2h-wyI4SqIigskyJNAeL2vSTJZU_Qp__;!!M-nmYVHPHQ!Y4hNxlUvhogHuTml9mLOFyubScjVzEeV9bplBPj_Hml9usrybcMGsXFQPiisBMCZ8siF6Mk$>

Please feel free ask questions as the pop up.

Hi Elliott,

Watching it now, this video is super super helpful, thanks for sharing. I was however thinking more about day to day maintenance issues, maybe that topic is not quite as sexy for a youtube video 😀   Maybe I should make one once I have become a bit more experience under my belt.

Not only if you want to understand LWTs, but also to get a better understanding of the sometimes-unintuitive consistency promises made and not made for non-LWT queries.
