### What's the problem 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. ### How to solve StarRocks is not support Decimal as primary key, so decimal should be cast to INT, BIGINT, LARGEINT or VARHCAR. If scale == 0, cast parse to INT, BIGINT, LARGEINT * Int is range from [-2,147,483,648, 2,147,483,647], some data with precision of 10 is out of range. * BigInt is range from [-9,223.372,036,854,775,808~9,223.372,036,854,775,807], some data with precision of 19 is out of range.(like unsigned big int from mysql) * LargeInt is range from [-1.701411835E38 ~ 1.701411835E38], some data with precision of 38 is out of range. -- This is an automated message from the Apache Git Service.
