[jira] [Commented] (HIVE-3746) TRowSet resultset structure should be column-oriented

    [ https://issues.apache.org/jira/browse/HIVE-3746?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13600342#comment-13600342 ] 

Carl Steinbach commented on HIVE-3746:
--------------------------------------

bq. However, any client trying to return rows one-at-a-time to an application would be required to read, process, and buffer almost an entire reply-worth of data before being able to return the first complete row.

The client is able to specify the maximum number of rows that should be returned in each fetch request. This is true regardless of whether we use a column-major or row-major format for the row data. Please refer to the definition of TFetchResultsReq in TCLIService.thrift for more information.
