Hi folks, we are looking for replacements of our prometheus backend and loki. Now we are comparing GreptimeDB with VictoriaMetrics/Victorialogs, is there any insights performance/scalability-wise from the community?

Checkout the benchmark on jsonbench https://jsonbench.com/#eyJzeXN0ZW0iOnsiQ2xpY2tIb3VzZSAobHo0KSI6dHJ1ZSwiQ2xpY2tIb3VzZ[…]lXSwicmV0YWluX3N0cnVjdHVyZSI6eyJ5ZXMiOnRydWUsIm5vIjp0cnVlfX0= Also compare with victoria, we are more cloud oriented, leveraging object storage and kubernetes, it's much easier to maintain and scale.

great, we are also interested in the data size, retention, compaction performance, etc. Will update here when we got some results

Regarding compaction performance, thanks to our object storage based architecture, in our enterprise version it's possible to off-load compaction workload to a dedicated process so it won't affect those foreground workload. Let me know if we can schedule a call before you kick-off your testing. We may be able to offer some tips ahead of time.
