…r DataStream API This commit implements the binlog-only newly added table capture feature for MySQL CDC DataStream connector, allowing dynamic table discovery without snapshot phase. Key changes: - Add new config option 'scan.binlog.newly-added-table.enabled' in MySqlSourceOptions - Add scanBinlogNewlyAddedTableEnabled field and getter in MySqlSourceConfig - Implement table pattern conversion from Flink CDC style to Debezium style in MySqlSourceConfigFactory - Add validation logic to ensure binlog-only mode works only with stream-only startup modes - Enhance BinlogSplitReader to auto-capture newly added tables matching the pattern - Add logging in MySqlSnapshotSplitAssigner for binlog-only mode - Expose scanBinlogNewlyAddedTableEnabled() API in MySqlSourceBuilder The feature converts table patterns (e.g., "db.table_\.*") to Debezium regex style (e.g., "db\.table_.*") and enables dynamic table discovery during binlog reading phase without triggering snapshots.

This commit implements the binlog-only newly added table capture feature for MySQL CDC DataStream connector, allowing dynamic table discovery without snapshot phase.
Key changes:
Add new config option 'scan.binlog.newly-added-table.enabled' in MySqlSourceOptions
Add scanBinlogNewlyAddedTableEnabled field and getter in MySqlSourceConfig
Implement table pattern conversion from Flink CDC style to Debezium style in MySqlSourceConfigFactory
Add validation logic to ensure binlog-only mode works only with stream-only startup modes
Enhance BinlogSplitReader to auto-capture newly added tables matching the pattern
Add logging in MySqlSnapshotSplitAssigner for binlog-only mode
Expose scanBinlogNewlyAddedTableEnabled() API in MySqlSourceBuilder
The feature converts table patterns (e.g., "db.table_.") to Debezium regex style (e.g., "db.table_.")
and enables dynamic table discovery during binlog reading phase without triggering snapshots.
