Hi Dojo,
I have local DMA and Cassandra that gets installed by DMA installer 10.2. My DMA version is 10.4.6. I would like to update my Cassandra to newer version, ideally I would remove Cassandra completely and install new version. I don't care about any data in the DB but I'm not sure if DMA will care or if I can just point it to the new Cassandra and it will automatically setup everything it needs on the new DB.
Where can I find information about supported Cassandra versions?
I've also been trying to setup Cassandra to use TLS and generating certificates with the script that is mentioned in the DataMiner docs however that script doesn't seem to work. It does generate certificates but Cassandra refuses to run with them. Is generate-tls-certificates repo still up to date and useable?
I also had issues with "curl https://localhost:9042" where it returns HTTP0.9. Is this expected response from Cassandra or is it an issue with my cassandra.ymal configuration?
Thanks
Hi Bert,
Thanks for the tip, but since I’m using it for experimenting and playing around I would like to avoid incurring additional cost for those purposes.
Cheers
Hi,
Depending on where you have the Cassandra instance installed, different versions can be used. If you are running Cassandra on Windows, it's not possible to update to Cassandra 4.0 or newer. If you are running Cassandra on Linux, you should be able to update to any version withing the 4.x range.
For the TLS, the script should still be working and is actively maintained. Can you please share the errors you get when using certificates generated by the script?
Kr,
I was thinking about installing Docker and running Cassandra 4 on it, would that work? How big of performance hit would it be?
Not sure about Docker but you could try to use WSL to run cassandra.
However, if I were you I would start looking at STaaS, especially if it’s only for some experimenting. The time spent setting up and maintaining Cassandra will far outweigh the small cost of using STaaS.
Hi Seppe,
Thank you for your patience and assistance. I’ve decided to move to STaaS and I must say I’m impressed how fast and easy it was, especially considering I’ve spent at least 40 hours trying to setup TLS on both Cassandra and Opensearch since your BPA Kata. In contrast, STaaS took about 5 minutes. At least I learned a lot… #copium
FYI: it’s now recommended to use STaaS, this will immediately solve all your questions here and you’ll have more time and more compute resources again to focus on other things.
