Subject How to measure the write amplification of C*?
Date Thu, 10 Mar 2016 06:18:27 GMT
Hello there,

I'm wondering is there a good way to measure the write amplification of
Cassandra?

I'm thinking it could be calculated by (size of mutations written to the
node)/(number of bytes written to the disk).

Do we already have the metrics of "size of mutations written to the node"?
I did not find it in jmx metrics.

Thanks
