Daniel Norberg commented on CASSANDRA-5422:
-------------------------------------------
I amended the commits to restore/add the apache license in the source files and
force pushed those branches.
Would Spotify signing the corporate CLA be enough or do we also need to assign
copyright to the ASF?

> With MutationStatement.execute turned into a no-op, I only get about 33k
> insert_prepared ops/s on my laptop. That is: this is an upper bound for our
> performance if Cassandra were infinitely fast, limited by netty handling the
> protocol + connections.
> This is up from about 13k/s with MS.execute running normally.
> ~40% overhead from netty seems awfully high to me, especially for
> insert_prepared where the return value is tiny. (I also used 4-byte column
> values to minimize that part as well.)
