Changelog for Oracle CDC Source Connector for Confluent Platform

Version 2.14.10

CC-35365: Enhanced error handling and reporting for failures caused by DDL changes to tables or partitions during snapshots.
CC-33954: Enhanced the connector to fail with a clear, actionable error message when attempting to snapshot tables with LOB columns that do not have a primary key.

CC-34077 - Fixed a bug that prevented the connector from retrying recoverable exceptions caused due to closed database connection, resulting in task failure.

CC-33611: Fixed a bug that could result in intermittent data loss when the connector is in a paused state and ingesting changes from captured tables.
CC-33153: Enhanced logging to better detect rollback of transaction changes.

CC-32868: Fixed a bug to use precision for the mapped DECIMAL data type in the connect schema when specified in the source schema for the NUMBER data type.
CC-32540: Added a fix to make LOB columns optional in connect schema to avoid compatibility issues when LOB columns are required in source schema.

CC-30327: Fixed a bug where the connector checked redo log file consistency for closed threads.
CC-31390: Added support for tables with virtual columns. Virtual column values are captured during snapshot and set to null during streaming.

CC-31044: Fixed a bug that caused the connector to retry adding redo log files to the log mining session using a closed database connection.

CC-30305: Added a new option write for the behavior.on.unparsable.statement configuration. This option logs the unparseable statement and writes it to the corruption topic specified by redo.log.corruption.topic. If write is enabled but redo.log.corruption.topic is not configured, it defaults to the log option.
CC-29797: Fixed a bug that caused the connector to stall when the in-memory queue was closed while handling long running transactions.

CC-29706: Optimized the snapshot process for very large tables by removing the need to execute a count query to determine the total number of rows.

CC-29193: Upgraded Protobuf Java Lite and Full library from 3.21.7 to 3.25.5 to address CVE CVE-2024-7254.
CC-28160: Added logic to throw a meaningful exception if the user lacks permission to query the V$LOGMNR_CONTENTS view.

CC-20297 – Improved error messages for redo log mining to include contextual information, such as redo log file names.
CC-19867 – Fixed a bug that caused the connector to stall when encountering tables with empty partitions while snapshot.by.table.partitions is set to true.
CC-21887 – Fixed a bug that prevented the connector from snapshotting newly added partitioned tables when snapshot.by.table.partitions is set to true.
