URL: https://github.com/apache/arrow/issues/47327
### Describe the enhancement requested
We have many nested list types and are using joins. However, it seems that
joins on list fields are currently not supported, even when they are non-key
fields. Will list field joins be supported in the future?
// relevant code:
for (const auto& field : left_schema.fields()) {
const auto& type = *field->type();
if (!IsTypeSupported(type)) {
return Status::Invalid("Data type ", type,
" is not supported in join non-key field ",
field->name());
}
}
for (const auto& field : right_schema.fields()) {
const auto& type = *field->type();
if (!IsTypeSupported(type)) {
return Status::Invalid("Data type ", type,
" is not supported in join non-key field ",
field->name());
}
}
