Influx HA cluster pricing is very expensive for our data size, which is sub 100G data. For a 3 node cluster, influx is charging $18,000 per annum.<p>https://influxdata.com/pricing/#product_subscriptions<p>We really like influx and heavily use the dimensioning feature in the TSD. Are there any influx like alternatives that are cheaper? I am willing to allocate $3,000 - $5,000 dollars (per annum) for this.
First question: Do you really need a cluster? We were running InfluxDB with a lot more data and ran on a single node. A single machine is surprisingly scalable.<p>If you are positive that you need a cluster, here are my suggestions:
* Recently Elasticsearch has become a lot better at time series data, so it might be worth a try.
* My second bet would be Cassandra. Look at these slides for more info: <a href="http://de.slideshare.net/patrickmcfadin/time-series-with-apache-cassandra-long-version" rel="nofollow">http://de.slideshare.net/patrickmcfadin/time-series-with-apa...</a>
Not sure if this is supported by Grafana, though.
* Another one would be Prometheus which also works with Grafana. Personally I'm not a big fan of its query language. Also clustering support is pretty limited there (and mostly needs to be handled by the client).
