Dan Burkert commented on KUDU-1458:
-----------------------------------
Did a quick survey: in Oracle and Postgres, truncate operations are not
MVCC-safe. Relevant docs:
https://www.postgresql.org/docs/9.1/static/sql-truncate.html,
https://docs.oracle.com/cd/E11882_01/server.112/e41084/statements_10007.htm#CHDDGIHF.
[~mpercy] besides transactionality, is there a reason to do this at the
tablet level instead of whole-sale replacing the tablets?

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