Hi Sachin, Currently, Flink CDC still uses Debezium 1.9.8.Final with various backported patches, most of them are monkey-patched files located in the `io.debezium` package. We were stuck at 1.x for a long time because Debezium 2.0+ requires at least Java 11.
There is an open JIRA ticket, FLINK-36605 [1], aiming to upgrade Debezium to 2.7. As FLINK-38730 [2] has dropped Flink CDC's Java 8 support, this ticket seems doable now.
