Description

Updates the mdn.legacy_{action,page} views to avoid NULL values on these three fields:

  • page URL
  • page referrer
  • subscription type

(The reason is that we have several existing queries that filter with LIKE '{{ param }}' where param is a query parameter defaulting to %, and NULL LIKE '%' is false.)

Related Tickets & Documents

  • (none)

Reviewer, please follow this checklist

Ensures that these rows are returned when filtering with `LIKE '%'`.
