             Summary: Throw an error when BigDecimal precision overflows.
                 Key: FLINK-25434
                 URL: https://issues.apache.org/jira/browse/FLINK-25434

    Affects Versions: 1.14.2
            Reporter: Ada Wong


 

Lost a lot of data but no error was thrown.

As the following comment, If the precision overflows, null will be returned.
{code:java}
/**
 If the precision overflows, null will be returned.
 */
public static @Nullable DecimalData fromBigDecimal(BigDecimal bd, int precision, int scale) {
    bd = bd.setScale(scale, RoundingMode.HALF_UP);
    if (bd.precision() > precision) {
        return null;
    }

    long longVal = -1;
    if (precision <= MAX_COMPACT_PRECISION) {
        longVal = bd.movePointRight(scale).longValueExact();
    }
    return new DecimalData(precision, scale, longVal, bd);
} {code}
