---------------------------------
Summary: Iceberg sink has an incorrect type conversion
Key: FLINK-38141
URL: https://issues.apache.org/jira/browse/FLINK-38141
Project: Flink
Issue Type: Bug
Components: Flink CDC
Affects Versions: cdc-3.4.0
Reporter: ZhangChao
According to the Iceberg documentation
https://iceberg.apache.org/docs/nightly/flink/#flink-to-iceberg, the CDC type
{{TINYINT}} should be mapped to the Iceberg type {{{}INTEGER{}}}. However, in
the code implementation of the Iceberg sink, I noticed that {{TINYINT}} is
actually mapped to the Iceberg type {{{}BOOLEAN{}}}.
