<!-- Please specify the module before the PR name: [core] ... or [flink] ... --> ### Purpose <!-- Linking this pull request to the issue --> Linked issue: close #4783 <!-- What is the purpose of the change --> We use ticdc to collect data from tidb to kafka, but it does not provide specific parameters for types. No length for varcahr, and no precision and scale for decimal. The current schema evoluation would improve them to string and decimal(38, 18), which is not expected. So we want to keep the type specified manually unchanged. This could be controlled by the new type_mapping options. NO_CHNAGE, DECIMAL_NO_CHANGE. ### Tests <!-- List UT and IT cases to verify this change --> Observe the varchar and decimal field definition after new value ingested. ### API and Format <!-- Does this change affect API or storage format --> No. ### Documentation <!-- Does this change introduce a new feature --> Yes, and provided. -- This is an automated message from the Apache Git Service.
