Subject: [Tarantool-patches] [PATCH 2/2] sql: make constraint operations transactional
Date: Tue, 12 Nov 2019 17:02:59 +0300	[thread overview]
Message-ID: <792e035b34839371b2fae03d91c782ebbe04c27c.1573566885.git.roman.habibov@tarantool.org> (raw)
In-Reply-To: <cover.1573566885.git.roman.habibov@tarantool.org>

Put constraint names into the space's hash table and drop them on
commit, replace and drop (in the alter.cc triggers).

Closes #3503
