This closes FLINK-35762. As previously discussed offline with @lvyanquan, HashMap lookup could be slow since we must calculate key hash code every time, though most key objects are immutable. A common practice in Java world is caching object hash code in a transient field, just like what `java.lang.String` does. In CDC code, `TableId` & transform rule types are frequently used as HashMap key type, and their hash code could be safely cached since their instances are immutable. -- This is an automated message from the Apache Git Service.
