**What**: Dry-run, audit results, then run for real the `updateVarDumps.php` script for AbuseFilter
**When**: Whenever [[https://gerrit.wikimedia.org/r/#/c/mediawiki/extensions/AbuseFilter/+/482499|this patch]] reaches production. I'm creating this task as a placeholder for now.
**Why**: To kill many layers of back-compat and a lot of tech debt (see parent task).
**Where**: All wikis - beta cluster first, then production.
**Who**: Whoever wants to do that. (@Daimona can do the Beta Cluster part).
# First of all, run `updateVarDumps.php --dry-run` and post the results.
# @Daimona will audit the results
# If necessary, we may have to re-run the script with `--dry-run-verbose` for selected wikis, then repeat (2.)
# Find a DateTime suitable for both of us
# Time to run it for real. The ideal steps are:
## Measure the size of the abuse_filter_log table (on enwiki?); measure the size of the ExternalStore (I don't know whether it's feasible)
## Run the script!
## Measure the sizes again and check how much space was saved.
