[jira] [Commented] (KUDU-1458) truncate table support for kudu tables

    [ https://issues.apache.org/jira/browse/KUDU-1458?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15532534#comment-15532534 ] 

Mike Percy commented on KUDU-1458:
----------------------------------

I think we should be able to just make some changes to internals at the tablet level to support a truncate operation which would remove all data from the tablet in one shot without modifying partition information. A "delete everything" operation could be implemented as a type of Transaction at the TabletPeer level.

> truncate will come in handy to quickly erase the table. current delete statement takes long time when the record count is high.
