What's changed and what's your intention?

The bug will affect Mysql CDC if the MySQL table time zone is not UTC

  • fix MySQL image version. We do not support MySQL 8.4
  • remove incorrect MySQL CDC param.

Such columns are converted into an equivalent io.debezium.time.ZonedTimestamp in UTC based on the server (or session’s) current time zone.

The default param connectionTimeZone will be server. That mean it will convert time column by the session timezone param. If set to '+00:00', debezium will assume the server timezone is '+00:00'

Since there will be corner cases for connectionTimeZone=SERVER , we will use connectionTimeZone=+00:00 and forceConnectionTimeZoneToSession=true

close #16496

This will actually affect other potential mysql test running in parallel, do you have any suggestion on addressing this? @xxchan

If really needed, you can write the old value to some tmp file, and restore it at the end.

I think many source tests can only be run in serial...
