Is there a free/open-source download for RiakTS?

Or can anyone recommend something lighter-weight than full-blown Kafka etc.?

Maybe, just maybe, someday basho will open the source for RiakTS, like what they did for RiakCS (Riak S2). Well, I certainly hope so :)

It isn't near as scalable as Riak, as the so-called clustering tops out at 3 nodes, but Influx is very very nice if you don't put gobs of data at it:

Riak is one of those systems, where it really does scale out linearly.

Things are actually about to get dramatically better for InfluxDB: https://influxdb.com/blog/2015/10/07/the_new_influxdb_storag...

I'm not sure how that helps fix the HA/FT clustering setup?

I can hurl more data at the system and have it go unavailable during a partition or lose updates when it heals?

Thanks for the heads up. As a current influx (and cassandra) user, I'm painfully aware of the limitations at "scale". Influx seems to be the best long term play, but still has some growing up to do.

I've had a good experience with Cassandra for times series data.

Likewise, but it doesn't solve one of the things that Riak TS and other timeseries DB's appear to try to solve: querying your data across ranges without knowing the range ahead of time. Essentially you are performing rollups yourself (which requires internal knowledge about how to aggregate values) to not scan gazillions of records to get a month's worth of data. Among other solutions, I believe this is something KairosDB[1] specifically tackles.
