This will hopefully not be needed, depending on the impact of deploying watchlist expiration.
Hello, @eprodromou! You can follow progress regarding our conversations with the DBAs (and, consequently, whether or not any changes will need to be made to the watchlist expiry feature or the ability to store more data in the watchlist table) in T261005. Currently, we have received the go-ahead from the DBAs for our plan, so no additional work is necessary to determine changes to the watchlist table at the moment. The plan is to incrementally release to a group of pilot wikis. The DBAs will then monitor if the introduction of the feature impacts the table and if any further adjustments must be made. So, in short, we can hold off on looking into accommodating more data in the watchlist table until we hear word from the DBAs on next steps in T261005. Thanks!
