-------------------------------------
Hi, I'm currently working on this issue, I have modified
[cassandra/conf/cassandra.yaml|https://github.com/apache/cassandra/blob/trunk/conf/cassandra.yaml#L932]
internode_compression option to dc only. Could you tell me if there are other
changes required? Also I'm working on {{trunk}}, is that fine?
> Disable internode compression by default

> Internode compression increases GC load, and can cause high CPU utilization
> for high throughput use cases. Very rarely are customers restricted by
> intra-DC or cross-DC network bandwidth. I'de rather we optimize for the 75%
> of cases where internode compression isn't needed and then selectively enable
> it for customers where it would provide a benefit. Currently I'm advising all
> field consultants disable compression by default.
