What is the captured database version and mode of depoyment?

Oracle 19c PDB

What behaviour do you expect?

The signaling data collection shouldn't be included in the snapshot process.

What behaviour do you see?

The signaling data collection is included in the snapshot process.

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

Database table 'ASEX92A.dbzusr.DEBEZIUM_SIGNAL' not configured with supplemental logging "(ALL) COLUMNS"; only explicitly changed columns will be captured. Use: ALTER TABLE dbzusr.DEBEZIUM_SIGNAL ADD SUPPLEMENTAL LOG DATA (ALL) COLUMNS

-> Is it really necessary to add supplemental logging for this table?

Only captured tables schema should be captured, capturing: [ASEX92A.ASEDBUSR.ABRDVRS, ASEX92A.ASEDBUSR.ABRDVRSUNT, ASEX92A.dbzusr.DEBEZIUM_SIGNAL]
