%description
Promscale is a horizontally scalable and operationally mature analytical
platform for Prometheus data that offers the combined power of PromQL
and SQL, enabling developers to ask any question, create any dashboard,
and achieve greater visibility into their systems.  Promscale is built
on top of TimescaleDB, the relational database for time-series built on
top of PostgreSQL.
