All events in Edit_5563071 appear to have the same value for event_pageViewSessionId (2147483647).

When fixing, we will want to bump the event_version value.

All events in Edit_5563071 appear to have the same value for
event_pageViewSessionId (2147483647).

It was simply overflowing its column type (int). I set it to 'bigint' and it's fine now.

It's odd that we haven't run into this before! It's because we ordinarily convert timestamps to byte strings, like the rest of MediaWiki. This is the first time we've tried to save timestamps as integers. The int type is good for values between +/- 2,147,483,647, which has been adequate for all other use cases.

When fixing, we will want to bump the event_version value.

Well, since this did not require a deployment, I instead moved all existing rows in the 'Edit' table to 'z_Edit_5563071'. Any events that go into the current 'Edit_5563071' will be fine.

Merged and we'll get this out on Monday so we can test it.
