CrateDB + Prometheus
CrateDB is a hyper-fast opensource distributed database technology that combines the best out of the SQL and NoSQL worlds. It supports the PostgreSQL wire protocol for easy integration with many data engineering tools.
Many IT systems, including Docker, expose systems monitoring metrics to Prometheus for short-term storage and time series dashboarding. Prometheus is a single-server datastore, which makes it easy to setup, but also limits the amount of data it can process to that one machine.
In order to support Prometheus long-term storage of time series data, Prometheus supports external storage solutions. The CrateDB Prometheus Adapter seamlessly connects those same IT systems to CrateDB via the Prometheus remote read/write request interface. This gives users a fault-tolerant way to scale their IT metrics data to hold months, or even years of time series data and analyze it using SQL.
