Just exploring this for devops at work. This comment makes me a little worried. Is there a risk that some features will go 'enterprise only' in future?

Our enterprise offering is for HA and scale out clusters of InfluxDB.

InfluxDB single server, Telegraf, Kapacitor single server, and soon Chronograf are all open source.

We'll continue to heavily develop our open source projects in addition to developing closed source software that we can license to customers. Basically, to be able to continue open source development, we need to have paying customers.

I don't understand the part of paying customers. Why couldn't you further develop clustering for open source version, as it was first promised and still have paying customers? There are many working examples doing this. Also, this is not a good example for OSS to do as you did with open source/enterprise and clustering bit. At least some explanation or vision could have been provided afterwards.

Who knows, they've done it before so they could potentially do it again.
