### Search before asking - [x] I had searched in the [issues](https://github.com/apache/seatunnel/issues?q=is%3Aissue+label%3A%22bug%22) and found no similar issues. ### What happened By default, Oracle does not synchronize data in CLOB format. I attempted to add this advanced parameter "debezium.lob.enabled=true". However, if a CLOB column has no changes, the result of synchronizing the data to the target table would be: "__debezium_unavailable_value". <img width="3142" height="1008" alt="Image" src="https://github.com/user-attachments/assets/97f7cdf7-a8e1-4865-b705-46674b676c65"; /> The commit of debesium DBZ-4321 seems to have fixed this issue. It is recommended to upgrade the debesium version to 2.5.0 Final or above. ### SeaTunnel Version 2.3.12 ### SeaTunnel Config ```conf { "env": { "shade.identifier": "base64", "job.mode": "STREAMING", "parallelism": 1, "job.name": "oracle-cdc2mysql-lob开启", "checkpoint.interval": 10000 }, "source": [ { "username": "ZHdzY2Rj", "password": "cHJpbWV0b24wMDAwMDA=", "plugin_name": "Oracle-CDC", "result_table_name": "CDCSource1770778672419", "database-names": [ "ORCL3" ], "table-names": [ "ORCL3.DWSCDC.USERINFO2_C" ], "table-names-config": [ { "table": "ORCL3.DWSCDC.USERINFO2_C", "primaryKeys": [ "USERCODE" ] } ], "base-url": "jdbc:oracle:thin:@127.0.0.1:1521:orcl3sid", "startup.mode": "latest", "exactly_once": true, "debezium": { "lob.enabled": "true" }, "format": "default", "schema-changes.enabled": false, "schema-names": [ "DWSCDC" ], "handle_blob_as_string": true, "use_select_count": false, "skip_analyze": false, "decimal_type_narrowing": false } ], "transform": [], "sink": [ { "user": "cm9vdA==", "password": "cHJpbWV0b24wMDAwMDA=", "url": "jdbc:mysql://127.0.0.1:3306/dwstest?allowPublicKeyRetrieval=true&nullCatalogMeansCurrent=true&serverTimezone=GMT+8&allowLoadLocalInfile=true&useSSL=false", "driver": "com.mysql.cj.jdbc.Driver", "database": "dws_720", "table": "USERINFO2_C", "exactlyOnce": false, "plugin_name": "Jdbc", "source_table_name": "CDCSource1770778672419", "connection_check_timeout_sec": 30, "max_retries": 3, "batch_size": 1000, "batch_interval_ms": 1000, "is_exactly_once": false, "generate_sink_sql": true, "max_commit_attempts": 3, "transaction_timeout_sec": -1, "auto_commit": true, "schema_save_mode": "CREATE_SCHEMA_WHEN_NOT_EXIST", "data_save_mode": "APPEND_DATA", "field_ide": "ORIGINAL", "use_copy_statement": false, "handle_blob_as_string": true, "primary_keys": [ "USERCODE" ] } ] } ``` ### Running Command ```shell ./seatunnel.sh --config /opt/seatunnel/jobs/oracle-cdc2mysql.json ``` ### Error Exception ```log no exception ``` ### Zeta or Flink or Spark Version _No response_ ### Java or Scala Version _No response_ ### Screenshots _No response_ ### Are you willing to submit PR? - [ ] Yes I am willing to submit a PR! ### Code of Conduct - [x] I agree to follow this project's [Code of Conduct](https://www.apache.org/foundation/policies/conduct) -- This is an automated message from the Apache Git Service.
