let repo-stream loose on 173K real atproto repos and it broke 3M records/sec, averaging around 2M/s.
(this is: reading CARs, validating blocks, walking and validating the MSTs, emitting and counting all repo keys)

some atproto repo size numbers from an ~80k sample, in case you need to plan for idk full network backfill or something
85% of repos are <1MiB (as CARs)
<5MiB: 95%
10: 98%
20: 99.2%
32: 99.7

i have never seen mentions in bsky posts outpace *likes* globally. spam wave or somehow organic?
this is a log scale: normally bsky likes are 10x(!) more frequent than mentions in posts: this peak just hit >200x the normal baseline mention rate

zooming way in on network metrics from the host, there was a very short network throughput drop. i wonder if maybe it was just some provider networking problem leading to PDS connections being dropped?
along with the gap in metrics being able to scrape, a network problem is my top suspect.

follow-up: it's a weird one. relay logs are out of retention unfortunately so i'm not sure if i'll get to a full root-cause.
the server did not reboot, the relay container stayed up. dmesg on the host has nothing since oct 25
pds hosts connected dropped abruptly and there are some gaps in metrics

ah! suspicion confirmed.
floating-point numbers are not support in the atproto dag-cbor data model, so these records are invalid. put floats in strings and parse them out where needed :(
unfortunately current pds and relay still admit some kinds of invalid data (allowed in cbor but not dag-cbor)
