Subject: [Tarantool-patches] [PATCH vshard 02/11] storage: add helper for local functions invocation
Date: Tue, 23 Feb 2021 01:15:40 +0100
Message-ID: <5530ed726e56702c79f70567c6e22f29eec32a8b.1614039039.git.v.shpilevoy@tarantool.org> (raw)
In-Reply-To: <cover.1614039039.git.v.shpilevoy@tarantool.org>

Function local_call() works like netbox.self.call, but is
exception-safe, and uses cached values of 'netbox.self' and
'netbox.self.call'. This saves at least 3 indexing operations,
which are not free as it appeared.

The cached values are not used directly in storage_call(), because
local_call() also will be used from the future function
storage_map() - a part of map-reduce API.

Needed for #147
