-------------------------------------
Summary: Truncate for Transactional tables should use base_x
Key: HIVE-20137
URL: https://issues.apache.org/jira/browse/HIVE-20137
Project: Hive
Issue Type: Improvement
Components: Transactions
Affects Versions: 3.0.0
Reporter: Eugene Koifman
This is a follow up to HIVE-19387.
Once we have a lock that blocks writers but not readers (HIVE-19369), it would
make sense to make truncate create a new base_x, where is x is a writeId in
current txn - the same as Insert Overwrite does.
This would mean it can work w/o interfering with existing writers.
