hi @cccs-br
Very sorry for delay!
Got sidelined with other stuff.
I was thinking to take this up, also spend some time initially, and reach to
a place where found that:
looks like `org.apache.iceberg.expressions.Literals.from` is the place where
`byte[]` or `ByteBuffer` converted to the corresponding literals
```
static <T> Literal<T> from(T value) {
Preconditions.checkNotNull(value, "Cannot create expression literal from
null");
Preconditions.checkArgument(!NaNUtil.isNaN(value), "Cannot create
expression literal from NaN");
if (value instanceof Boolean) {
return (Literal<T>) new Literals.BooleanLiteral((Boolean) value);
} else if (value instanceof Integer) {
return (Literal<T>) new Literals.IntegerLiteral((Integer) value);
} else if (value instanceof Long) {
return (Literal<T>) new Literals.LongLiteral((Long) value);
} else if (value instanceof Float) {
return (Literal<T>) new Literals.FloatLiteral((Float) value);
} else if (value instanceof Double) {
return (Literal<T>) new Literals.DoubleLiteral((Double) value);
} else if (value instanceof CharSequence) {
return (Literal<T>) new Literals.StringLiteral((CharSequence) value);
} else if (value instanceof UUID) {
return (Literal<T>) new Literals.UUIDLiteral((UUID) value);
} else if (value instanceof byte[]) {
return (Literal<T>) new Literals.FixedLiteral(ByteBuffer.wrap((byte[])
value));
} else if (value instanceof ByteBuffer) {
return (Literal<T>) new Literals.BinaryLiteral((ByteBuffer) value);
} else if (value instanceof BigDecimal) {
return (Literal<T>) new Literals.DecimalLiteral((BigDecimal) value);
}
```
Also discussed with @RussellSpitzer and next step was to check the query
plan in spark sql case. That can give more insight as how it's being handled in
case of spark sql.
thanks @RussellSpitzer for the help!
