> It seems there is a never ending supply of time series databases being written on top of Cassandra. Unless any of them are significantly better than KairosDB I'm not going to change the top 10.
I really appreciate the work Brian Hawkins has done with KairosDB. We settled on KairosDB at work after having a bunch of trouble with InfluxDB. At the same time, it's very much stuck in the Cassandra 2.1 world* . There have been some significant advancements with Cassandra for this particular use case (new storage engine, TWCS) and KairosDB is missing out.
*Yes, it can be run on 2.2.x by enabling the now-disabled-by-default Thrift, but that feels like a last gasp.
