Set default value for a field.

Hello,

We use Apache Arrow 2.0.0 java implementation for data transfer and
enrichment. Is there a way to set a default value for a Field? As of now we
iterate all indexes of a FieldVector and set the same value.

Ok.
Thanks for the clarification Micah.

That is the only way that I'm aware of doing it. The specification doesn't
allow for default values (there has been some prior discussion on adding
things like RLE to the specification but that is a major project).
