allow to override Base(Large)RepeatedValueViewVector

[rluvaton]

This is done as different arrow implementation have different default list item field name

For example, Rust implementation of Arrow (arrow-rs) has default value of item (https://github.com/apache/arrow-rs/blob/4f1f6e57c568fae8233ab9da7d7c7acdaea4112a/arrow-schema/src/field.rs#L125).

And according to the specification, the name of the list is not required to be a specific string. so to make it easier to use Java Arrow implementation with other implementation of Arrow, I'm making the DATA_VECTOR_NAME configurable

I will add tests after I know this change is desired and will be approved

Another solution that is good for me, is to allow changing the field name of existing list (as sometimes I'm not the one that creates the list but all the lists are coming through me, currently it is not possible as far as I can tell.

the only place I see in the codebase that do something like that is in:

arrow-java/vector/src/test/java/org/apache/arrow/vector/pojo/TestConvert.java

Line 97 in be627bf

String modifiedSchema = jsonSchema.replace("$data$", "[DEFAULT]");

which convert the schema to json, change the field name and create the schema again (making sure the new field name is used)

I think it'd make more sense to allow changing defaultDataVectorName for an instance? I'm not a big fan of mutable globals

Changing defaultDataVectorName for an instance is too late, no? as the instance already created

The child vector is created lazily, though

[rluvaton]

But it can still be too late, is there a way to change a field (or field name) of existing list?

[lidavidm]

I don't see how a mutable global lets you change the name of an existing list either, though.

Once the child is created I think you'd have to recreate the child instead of being able to mutate the name.

Do you have a sample to show the scenario you are concerned about?
