[jira] [Commented] (ARROW-1614) [C++] Add a Tensor logical value type with constant dimensions, implemented using ExtensionType

["Christian Hudon (Jira)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/ARROW-1614?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=17100808#comment-17100808 ] 

Christian Hudon commented on ARROW-1614:
----------------------------------------

Created ARROW-8714 for the varying dimensions case. Renamed this one to be clearer that it is about the constant dimensions case.

Is the approach proposed sound for this case? What would be a next step in terms of code? Is there an example of another type that's implemented as en ExtensionType that I could have a look at?

> In an Arrow table, conceivably a column could have values cells each containing a tensor value of some size (a binary value plus some metadata to store type and shape/strides)
