Data Model

A deeper look at Vector's data model

Event

As shown above, Vector generalizes all data flowing through Vector as "events":

event.proto
message EventWrapper {
oneof event {
Log log = 1;
Metric metric = 2;
}
}

You can view a complete definition in the event proto definition. You'll notice that each event must be one of 2 types:

FAQ

Why not just "event"?

  1. We like the "everything is an event" philosophy a lot.

  2. We recognize that there's a large gap between that idea and a lot of

    existing tooling.

  3. By starting "simple" (from an integration perspective, i.e. meeting people

    where they are) and evolving our data model as we encounter the specific

    needs of new sources/sinks/transforms, we avoid overdesigning yet another

    grand unified data format.

  4. Starting with support for a little more "old school" model makes us a better

    tool for supporting incremental progress in existing infrastructures towards

    more event-based architectures.
