Questions tagged [kairosdb]

KairosDB is a fast distributed scalable time series database written on top of Cassandra. It was initially a rewrite of the original OpenTSDB project, but it evolved to a different system for which data management, data processing, and visualization are fully separated.

KairosDB runs with java 1.6 or later.
