Hongshun Wang updated FLINK-34690:
----------------------------------
Description:
Flink only have bigint type, if mysql data is unsigned bigint , maybe out of
range, so cast to DECIMAL(20, 0).
If starrocks supports unsigned bigint, maybe can transform DECIMAL(20, 0) to
unsigned bigint in sink. To be honest, unsigned bigint is not in SQL standard,
thus many databases maybe not support it.
[https://docs.starrocks.io/zh/docs/sql-reference/sql-statements/data-types/data-type-list/]
And starrock not support DECIMAL as primary key, thus should be transformed to
String. I think we can fix it.
was:If data from upstream is decimal and primary key , starrocks sink will
not support.
