> 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
> Priority: Major
> Labels: CDC, Sink, iceberg
>
> 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{}}}.
