What behaviour do you expect?

Comment and DDL should be separated and behaved accordingly. 

What behaviour do you see?

Both comment and DDL processed as comment. The DDL is below. All DDL file is skipped. Here is the DDL:

# Create the new ENTITY table which will be the parent of all other resource tables.
CREATE TABLE IF NOT EXISTS ENTITY (
ID BIGINT AUTO_INCREMENT PRIMARY KEY,
ENTITY_UUID VARCHAR(255) NOT NULL,
ENTITY_TYPE VARCHAR(255) NULL,
CREATED_ON DATETIME(6) NULL,
UPDATED_ON DATETIME(6) NULL,
CREATED_BY VARCHAR(255) NULL,
UPDATED_BY VARCHAR(255) NULL,
CONSTRAINT UI_NETWORK_ENTITY_UUID UNIQUE (ENTITY_UUID)
);

Here is the log in debezium

Do you see the same behaviour using the latest relesead Debezium version?

(Ideally, also verify with latest Alpha/Beta/CR version)
2.3.2.Final also has same issue.

Do you have the connector logs, ideally from start till finish?

(You might be asked later to provide DEBUG/TRACE level log)

Yes

How to reproduce the issue using our tutorial deployment?

Just run the connector
