Subject Re: scylladb

I dont think ScyllaDB performance is because of C++. The design decisions
in scylladb are indeed different from Cassandra such as getting rid of SEDA
and moving to TPC and so on.

If someone thinks it is because of C++ then just show the benchmarks that
proves it is indeed the C++ which gave 10X performance boost as ScyllaDB
claims instead of stating it.
