[jira] [Commented] (KUDU-1694) C++ client support for specifying tuple memory layout

    [ https://issues.apache.org/jira/browse/KUDU-1694?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16562159#comment-16562159 ] 

Tim Armstrong commented on KUDU-1694:
-------------------------------------

I was looking at IMPALA-7367 as another example where we could make the tuple memory layout more efficient. We've have to special-case Kudu in IMPALA-7367 to insert additional padding.

> Transforming Kudu's tuples to another tuple format (e.g. Impala's tuple format) is expensive. The client should allow the output tuple format to be specified so that conversions aren't necessary.
