Utility method that will poll the CDC change tables and provide the record handler with the changes detected. The record handler can then make a determination as to whether to return true if the expected outcome exists or false to indicate it did not find what it expected. This method will block until either the handler returns true or if the polling fails to complete within the allocated poll window.

Parameters:

connection - the SQL Server connection to be used

tableName - the main table name to be checked

handler - the handler method to be called if changes are found in the capture table instance
