It seems that the vast majority of these open-source TSDBs are focused on fairly technical event stream data arising specifically from IT infrastructure... is anyone using them with success in more business-oriented domains, e.g. energy meter data, stock trading, other telemetry?
We were using InfluxDB for web analytics (generated by user interactions such as "viewed page", "viewed product", "refined search", etc.).
0.8 way okay, but very slow and unstable. But in 0.9 the data model is very different and no longer a good fit for this type of analytics (it looks great for devops metrics, though), so we're abandoning InfluxDB altogether.
We're now in the process of migrating to ElasticSearch, which is looking much better. ElasticSearch has its own problems, though, and we will be evaluating the same dataset in PostgreSQL soon.
