+Complemented some necessary but missed keys for the DynamoDB connector and the action.
+
+## Breaking changes
+* The old configuration no longer works, although it actually didn't work properly until this fix.
+* For DynamoDB connector, a new key `region` is necessary.
+* `hash_key` and `range_key` are now supported in the DynamoDB action, and `hash_key` is required.
