########## api/src/main/java/org/apache/iceberg/types/Types.java: ########## @@ -694,7 +698,10 @@ private static Literal<?> castDefault(Literal<?> defaultValue, Type type) { throw new IllegalArgumentException( String.format("Invalid default value for %s: %s (must be null)", type, defaultValue)); } else if (defaultValue != null) { - return defaultValue.to(type); + Literal<?> typedDefault = defaultValue.to(type); Review Comment: Right now, we make a lot of assumptions that Literal does not contain null or NaN. That way, we don't need to implement 3-value boolean logic or worry about how to handle NaN in comparisons. If you want to have a null default, then you don't set a default value for an optional column. And this also passes through null without a problem if the Literal was null. -- This is an automated message from the Apache Git Service.
