Won't this mean that multiple events (those produced during the same > http request at varnish level) will have the same reqid? That's the idea, yes, so that different requests that fire off in the system can be tied to the same request ID.

That's what EventLogging capsule does: > https://meta.wikimedia.org/wiki/Schema:EventCapsule I don't see a conflicting problem with `id` (even though `id` is a JSONSchema keyword, but it relates to the schema, not its properties, so we're good there). `uuid` is not a good choice, IMHO, it's like naming a field //string// because its value is a string. The most accurate name would be `reqid`, since that's what it is.

For webrequest data, the ISO8601 is called `dt`. That can be seen from the fields type, I guess: if it's integer, it's a unix time stamp, otherwise an ISO8601 date. But I see your point. Will `s/ts/dt/` in the description.

We could increase the schema version every time we change something in the schema. Easy to achieve but it's also easy to forget to bump the version when something has been changed. - Use the git commit SHA1. Here the event bus would attach the current git commit SHA1 to the message. Also rather straightforward to achieve. The problem here might be that different messages for the same topic might have different SHA1's, but still point to the same version of the schema.
