Eugene Koifman commented on HIVE-18124:
---------------------------------------
transactional=true makes the table transactional (and full acid).
Additionally there is transactional_properties properties which can have
"default" and "insert_only" values. "default" is a synonym for acid (for
backward compat). insert_only is 1/4 acid.
> clean up isAcidTable() API vs isInsertOnlyTable()

> With the addition of MM tables (_AcidUtils.isInsertOnlyTable(table)_) the
> methods in AcidUtils and dependent places are very muddled. There are now a
> number of places where we have something like _isAcidTable =
> AcidUtils.isFullAcidTable(table)_ and a later getter
> _boolean isAcidTable() \{ return isAcidTable;\}_
> Need to clean it up so that there is a isTransactional(Table) that checks
> transactional=true setting and isAcid(Table) to mean full ACID and
> isInsertOnly(Table) to mean MM tables.
> This would accurately describe the semantics of the tables.
