With features telemetry, there are counters for different SQL commands, such as ALTER TABLE or ALTER TABLE...ADD COLUMN. For schema changes, we should add counters for when they succeed, fail, or are canceled.

As a first pass, we can start with a counter per job type - meaning, schema changes / CDC /backup / etc.

Jobs can also have pending, running, or paused statuses. Since those are transient statuses, they are not as important to capture in telemetry data.

Once this is closed, please add a new issue for grouping these telemetry counters by schema change type.
