Their column store is really fast, but I am disappointed they did not mention what you lose: complex queries. You cannot do joins or combine data from separate events. For example if want to measure errors per active worker, as fraction of total load, all those fields have to be sent in same event to Honeycomb from the same service. This kind of question is answerable with promql, and other systems I have used.
It really like using Honeycomb vs Grafana + Prometheus for figuring out what is broken. I cannot wait until their dash boarding and alert/slo management mature enough that I don’t have to use separate products for it.
