Work on HIVE-14169 started by Sahil Takiar. ------------------------------------------- > Beeline Row printing should only calculate the width if TableOutputFormat is > used > --------------------------------------------------------------------------------- > > Key: HIVE-14169 > URL: https://issues.apache.org/jira/browse/HIVE-14169 > Project: Hive > Issue Type: Sub-task > Components: Beeline > Reporter: Sahil Takiar > Assignee: Sahil Takiar > Attachments: HIVE-14169.1.patch > > > * When Beeline prints out a {{ResultSet}} to stdout it uses the > {{BeeLine.print}} method > * This method takes the {{ResultSet}} from the completed query and uses a > specified {{OutputFormat}} to print the rows (by default it uses > {{TableOutputFormat}}) > * The {{print}} method also wraps the {{ResultSet}} into a {{Rows}} class > (either a {{IncrementalRows}} or a {{BufferedRows}} class) > * The {{Rows}} class will calculate the optimal width that each row in the > {{ResultSet}} should be displayed with > * However, this width is only relevant / used by {{TableOutputFormat}} > We should modify the logic so that the width is only calculated if > {{TableOutputFormat}} is used. This will save CPU cycles when printing > records out to the user. -- This message was sent by Atlassian JIRA (v6.3.4#6332)
