We recently wanted to deploy a change to eventlogging that would insert parsed user Agents in the user agent column on every table of eventlogging database.
This change increases the length of UA data and event_userAgent database column is limited by this setting:
- increase this length
- run an alter on all tables so event_userAgent column size is increased?
The issue with column length is blocking this ticket: https://phabricator.wikimedia.org/T153207
