---------------------------
Summary: Pipeline YAML should allow merging decimal with different
precisions
Key: FLINK-36565
URL: https://issues.apache.org/jira/browse/FLINK-36565
Project: Flink
Issue Type: Improvement
Components: Flink CDC
Reporter: yux
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.
