[jira] [Commented] (ARROW-1055) [C++] GPU support library development

["Siu Kwan Lam (JIRA)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/ARROW-1055?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16129015#comment-16129015 ] 

Siu Kwan Lam commented on ARROW-1055:
-------------------------------------

For starter, it will be great if there is a arrow serializer and deserializer that minimize host<->device transfer.  Initially, arrow needs to handle device memory pointer only and it doesn't need to deal with device IPC handles.   The schema is usually small that it is okay to be processed on the host side.  For the recordbatches, it is best to keep the payload on the device.
