CC-38740: Validate column mapping regexes against table.include.list entries

[KGaneshDatta]

Problem

A misconfigured regex in timestamp.columns.mapping (or incrementing.column.mapping) that doesn't match the tables in table.include.list is only caught at runtime, causing the connector to fail after startup. This error requires to be validated before so that the user can react upon it immediately.

Solution

Added config validation in JdbcSourceConnectorValidation that verifies each table.include.list entry matches exactly one regex in the column mapping configs. Differences are now shown as clear actionable validation errors before the connector starts.

Does this solution apply anywhere else?

• yes
• no

If yes, where?
