Cassandra configuration design doc

[john.sanda]

Hi folks,

A few days ago I created https://github.com/k8ssandra/k8ssandra/pull/109 which is a short design doc that discusses how we might expose various configuration settings for things like cluster topology and properties in cassandra.yaml and jvm.options.

The k8ssandra-cluster Helm chart currently exposes very little in terms of configuration in large part because we want to answer some questions:

• What settings should be exposed?
• What settings should not be exposed?
• How should settings be exposed?

I would love to get some feedback on the doc either here on this list or feel free to comment directly on the PR!

Thanks

John

Hi John

My requirements around configuration has been in 3 areas so far

1) creating a networktopology with 1 DC with option to add more

2) changes in cassandra.yaml around batch mode processing (to integrate ACID functionality of ScalarDB)

3) add -javaagent for MCAC 

Not sure if the above would help you in deciding about the configuration aspects

thanks

Hi Manu,

Thanks for the feedback! It is greatly appreciated :)

1) creating a networktopology with 1 DC with option to add more

This will definitely be supported.

2) changes in cassandra.yaml around batch mode processing (to integrate ACID functionality of ScalarDB)

Can you share some details or examples around this? 

 

 3) add -javaagent for MCAC 

MCAC is already deployed by default 

Thanks

John
