T222603: Fix oozie banner_impression monthly job
T208589: [EventLoggingToDruid] Add support for ingesting subfields of map columns
T203669: Return to real time banner impressions in Druid

See: T183978#5202071

As of this writing, the open tasks attached to this epic do approximate what needs to be done. Probably as we move forward we'll think of more specific ones related to parallel deployment of the new system and switching off of the old one.

we can wait, really. it is important but not urgent.

@Nuria, @Ottomata, the update to version number for the CentralNoticeBannerHistory schema should have been deployed to production last week with the Mediawiki deploy train. However, we had to roll back CentralNotice changes due to another, unrelated issue, which we are still working to fix. So the updated schema is not yet being used on production.

Of these modules, the following 7 modules are only used in the administration UI interface on Meta:

Here's the comment I just added to the in-page preview Gerrit change:

@Pcoombe, this should be live on production now... Can you confirm that it's working? Thanks much!!!!

Similar, though less specific, task, which we might merge in: T122589

@AndyRussG ping, not sure if anything happened on this.

@Ottomata Hi! I updated the CentralNotice schema. So, we'll also update the version number in the client code. Thanks!!

In case it's useful, here are details about how remind-me-later gets into civi. From the banner, a background POST is made to a URL like this:

Sorry for the delay...!! I thinks so... @Seddon, ok with you also that the existing data in Hive obtained from the new pipeline be deleted?

Let's see, this data comes from eventlogging, in order for it to be useful we need to make sure FR-tech has switched to eventlogging being the main way by which impressions are computed, has that happened?

Hi! Thanks so much!!!

FYI that this blocks some changes to improve refinement of data, cause until these schemas are changed they cannot be refined with the new code. Ping @AndyRussG

Columned my update.

It might be good for fr-tech to know that this exists and have links to it. However it's kind of a Seddon task. Fr-tech engineers should not attempt this without him.

Just to note, additional developer setup required for the fundraising vagrant role (such as perhaps specific XDebug stuff) should also be documented.

Here are the unfinished drafts from a while ago.

@AndyRussG, do you think it would be possible to check the headers in CentralNotice.hooks.php? When a banner header with a value of null is set, maybe we don't call $out->addModules( 'ext.centralNotice.startUp' );. This would disable the CentralNotice banner JavaScript from executing.
