Some question after reading the comparison with Cassandra tech paper

[at15]

Hi, after reading the Benchmarking InfluxDB vs. Cassandra for Time-Series Data, Metrics & Management paper I have some question about the benchmark.

It is said in the paper that a lot of application code are needed to get have Cassandra works as a tsdb. However there are KairosDB and Heroic which both support Cassandra, have u considered comparing with them?

The test is run on two dedicated machines. But Cassandra has a lot features for multi machine deployment like built in support for replication and consistent. It would be more convincing if InfuxDB is using its HA solutions to compete with Cassandra cluster.

Also some configuration on system and databases can effect performance a lot. Though it's too verbose to talk about them in the paper, I'd like to know how u choose those parameters, by running some smaller bench first?

Thanks
