Subject: [Tarantool-patches] [PATCH 6/7] iproto: implement interactive transactions over iproto streams
Date: Thu,  5 Aug 2021 21:17:44 +0300	[thread overview]
Message-ID: <06bcadd06bca14d32391e5612427b7b3f9084d26.1628184138.git.mechanik20.05.1988@gmail.com> (raw)
In-Reply-To: <cover.1628184138.git.mechanik20.05.1988@gmail.com>

From: mechanik20051988 <mechanik20.05.1988@gmail.com>

Implement interactive transactions over iproto streams. Each stream
can start its own transaction, so they allows multiplexing several
transactions over one connection. If any request fails during the
transaction, it will not affect the other requests in the transaction.
If disconnect occurs when there is some active transaction in stream,
this transaction will be rollbacked, if it does not have time to commit
before this moment.

Part of #5860

@TarantoolBot document
Title: interactive transactions was implemented over iproto streams.
The main purpose of streams is transactions via iproto. Each stream
can start its own transaction, so they allows multiplexing several
transactions over one connection. There are multiple ways to begin,
commit and rollback transaction: using IPROTO_CALL and IPROTO_EVAL
with corresponding function (box.begin, box.commit and box.rollback),
IPROTO_EXECUTE with corresponding sql request ('TRANSACTION START',
'COMMIT', 'ROLLBACK') and IPROTO_TRANSACTION_BEGIN, IPROTO_TRANSACTION_COMMIT,
IPROTO_TRANSACTION_ROLLBACK accordingly. If disconnect occurs when there is
some active transaction in stream, this transaction will be rollbacked, if it
does not have time to commit before this moment.
Add new command codes for begin, commit and rollback transactions:
`IPROTO_TRANSACTION_BEGIN 14`, `IPROTO_TRANSACTION_COMMIT 15` and
`IPROTO_TRANSACTION_ROLLBACK 16` accordingly.
