Hi all,

I would like to start a discussion about upgrading Debezium to version 2.x.

Background:
Currently, the Debezium community no longer maintains versions prior to
2.0,
and the website has taken down the documentation for versions before 2.0.
However, Flink CDC depends on Debezium version 1.9, and the documentation
references links to that version.


Problem:
- References to Debezium's documentation links report errors [1]
- The Debezium community will no longer maintain versions prior to 2.0.
Flink CDC
synchronizes bug fixes from Debezium 2.0 by overwriting classes, but the
classes differ significantly between 2.x and 1.9.


Compatibility and Deprecation:
- Debezium uses JDK 11 starting from version 2.0 [2]


Plan:
- Migrate references in Flink CDC documentation from Debezium 1.9 to 2.0
- Upgrade Debezium to version 2.x
