... even there it is not fully guaranteed that it won't cause issues. In Qtrace currently there's no protection whatsoever, but the message processing is very quick, so it's hard to overload it. It would be a nice future improvement to add some overload protection, , perhaps with...

I think the nature of `:trace` makes it borderline impossible to be completely safe for production. Because we potentially trace the whole VM, but can only have a single handler process, it can fall behind and the queue may grow. `:recon_trace` does some level of overload protection, but...

ASCII latency histogram

Why? In real world systems, your P99 and latency distribution often matter more than average times. Qtrace uses Erlang tracing to measure, with a low overhead, arbitrary function performance and output histograms and quantiles. Here's a sample output for `poolboy:checkout` during a simulated load:

we just dropped 7 new components in @supabase.com UI

This one's a bit different: it's a "Platform Kit" which you can use if you're providing Supabase projects/databases to your own users. It's like a UI wrapper on top of our Management API
