Review comment:
This test is skipped in
[precommits](https://ci-beam.apache.org/job/beam_PreCommit_Python_Commit/18696/testReport/apache_beam.io.external.xlang_debeziumio_it_test/)
it is running on portable postcommitIT tests. The other cross-language
transform tests run in the same way.

> An x-lang wrapper for DebeziumIO
> --------------------------------
>
> Key: BEAM-11838
> URL: https://issues.apache.org/jira/browse/BEAM-11838
> Project: Beam
> Issue Type: Bug
> Components: cross-language, io-java-debezium
> Reporter: Pablo Estrada
> Assignee: Benjamin Gonzalez
> Priority: P2
> Labels: stale-assigned
> Time Spent: 6h 10m
> Remaining Estimate: 0h
>
> DebeziumIO outputs data in JSON format by default, so it's a perfect
> candidate to be made available as a xlang transform.
> The DebeziumIO module provides a base to implement this, but for an
> effective, easy-to-use connector in Python, we will need the following things:
> * A new Java module that includes the per-database dependencies (Debezium's
> MySQL, Postgres, DB2, Oracle connector dependencies). This is necessary so
> that users can simply specify a database on the Python side, and the Java
> side will automatically provide the dependency.
> * A thorough review of the current default JSON output from DebeziumIO
> * A set of parameters to be received by the Python wrapper. Maybe we'll use
> the same format as the existing DebeziumIO (i.e. mandatory parameters: host,
> user, password; and keyword parameters)
>
> A short guide:
> [https://beam.apache.org/documentation/programming-guide/#mulit-language-pipelines]
> An example of this kind of change: [https://github.com/apache/beam/pull/12145]
