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"?

Hi,
I am able to reproduce the following Cassandra bug with version 3.3 and would
like to add more info to Jira like stack trace and debug log:
https://datastax-oss.atlassian.net/browse/JAVA-268
Can someone gime me temporary access to upload them and add my comments?
Thanks,

entry
Hi,
We have been investigating how to include in our 2i implementation the
ability to index TTL expirable Cells in Cassandra 3.x.
Reading comments in o.a.c.index.Index.Indexer.removeRows it seems that this
