Hi everybody,
the Analytics team is working on some alter tables to the Eventlogging 'log' database on analytics-store (dbstore1002) and analytics-slave (db1047) as part of https://phabricator.wikimedia.org/T167162.
The list of alter tables are the following: https://phabricator.wikimedia.org/P5570
This should be a transparent change but I thought it would have been better to keep all of you informed in case of unintended regressions or side-effects. The context of the alter tables is in T167162 but the TL;DR is that we need nullable attributes across all the EL tables (except fields like id, uuid and timestamp) to be able to sanitize data with our new eventlogging_cleaner script (https://phabricator.wikimedia.org/T156933).
Please let me know if you encounter any issue with this change.
Thanks in advance!
Luca
