As part of the Search Update pipeline work, we want to be able to measure impact and quantify the problem that we are trying to resolve.
More general discussion about the potential definition of SLO are at https://docs.google.com/document/d/1gYROXo8Fl7JSxReHAVI22EhcPvG-INVkq79a1C3tfK0/edit

There was a suggestion that we could use the average number of Sanetizer corrections over the Nov 2020 - Nov 2021 period: https://grafana.wikimedia.org/d/2DIjJ6_nk/cirrussearch-saneitizer-historical-fix-rate?orgId=1&from=now-2y&to=now

still blocked on gathering more data, sadly a lot of typos were made in this monthly dag (https://gitlab.wikimedia.org/repos/data-engineering/airflow-dags/-/merge_requests/465)
We should split this ticket between error rate and lag. Lag is easy to complete, but error will take longer.

Add metric to report lag from the consumer
