Is GreptimeDB suitable as a long-term storage solution for Prometheus? To find an answer to this question, I set up a simple configuration of GreptimeDB (v0.13) to investigate.
GreptimeDB is an open-source cloud-native time series database that integrates metrics, logs, and events.
Cortex, started by Tom Wilkie and Julius Volz (Prometheus’ co-founder) in 2016, has several interesting architectural features. As one of Prometheus’ long-term storage solutions, Cortex has been referenced by many time-series based storage architectures (tracing, log) since then (especially in the Grafana stack).
I created a simple presentation about Prometheus. I uploaded it using sporto/hugo-remark: A theme for using remark.js with hugo, and I found that creating it in markdown rather than PowerPoint allowed me to focus more on the content. (But that doesn’t necessarily mean the content is better.)
