Subject: [tarantool-patches] [PATCH v4 8/8] sql: remove global sql_trigger hash
Date: Tue, 26 Jun 2018 19:13:32 +0300	[thread overview]
Message-ID: <1d6bcf87b16c4b7c64eb82d3da43adfabede0a7e.1530029141.git.kshcherbatov@tarantool.org> (raw)
In-Reply-To: <81986d1f9307191bd3d3e37514dc32fadb7e6970.1530029141.git.kshcherbatov@tarantool.org>
In-Reply-To: <cover.1530029141.git.kshcherbatov@tarantool.org>

As new _trigger format contain space_id, we can do not
store AST pointers in HASH. Requested AST could be found
by name in appropriate space.

Part of #3273.
