Dynamically Apply values from enrichment table row

[aranade-anduril]

my enrichment table is very simple, just 2 rows

env,source,host
env1,source1,host1 #example values

and I want to tag every metric with the values in the second row.

Can I tag my metric with those fields without hardcoding env,source,host?

I do it like this right now, but it requires hardcoding of the above 3 values:

row, err = get_enrichment_table_record("additional_tags", {})
if err != null {
  log("Unable to get 'additional_tags' enrichment table: " + err, level: "error")
} else {
  .tags.env = row.env
  .tags.source = row.source
  .tags.host = row.host
}

Let's say the enrichment table is expanded in the future to support an additional column, I'd want to be able for my code to handle this without updating the VRL.

Hi @aranade-anduril, you can probably vector.dev/docs/reference/vrl/functions/#map_keys for this.
