> Project: Flink
> Issue Type: Improvement
> Components: Flink CDC
> Affects Versions: cdc-3.1.1

> Currently, it's not possible to merge two Decimal-typed fields with different
> precision or scaling. Since DECIMAL(p1, s1) and DECIMAL(p2, s2) could be
> converted to DECIMAL(MAX(p1 - s1, p2 - s2) + MAX(s1, s2), MAX(s1, s2) without
> any loss, this converting path seems reasonable and worth being added.
