Subject [jira] [Commented] (CASSANDRA-8888) Disable internode compression by default
Date Mon, 02 Mar 2015 18:14:04 GMT


Jonathan Ellis commented on CASSANDRA-8888:

It seems like a lot people have high anxiety about cross-dc bandwidth, justified or not. 
What about setting it to cross-dc compression only 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.
