Christian Hudon updated ARROW-8714:
-----------------------------------
Description:
Support for tensor in Table, RecordBatch, etc. where each row is a tensor of a
different shape (e.g images of different sizes), but of the same underlying
type (e.g. int32). Implemented as an ExtensionType, so no need to change the
format.
I don't see needing each row being a tensor with a different number of
dimensions, so if the implementation for that falls out easily of the use case
with each row in the table having a tensor with the same number of dimensions,
great. If it adds a lot of complexity, that case would be postponed.
> [C++] Add a Tensor logical value type with varying dimensions, implemented
> using ExtensionType
