Subject: [Tarantool-patches] [PATCH 8/8] replication: write and read CONFIRM entries
Date: Tue,  9 Jun 2020 15:20:20 +0300	[thread overview]
Message-ID: <3210e1e6f867cfd1c1f65e05f28a32deae63c172.1591701695.git.sergepetrenko@tarantool.org> (raw)
In-Reply-To: <cover.1591701695.git.sergepetrenko@tarantool.org>

Make txn_limbo write a CONFIRM entry as soon as a batch of entries
receive their acks. CONFIRM entry is written to WAL and later replicated
to all the replicas.

Now replicas put synchronous transactions into txn_limbo and wait for
corresponding confirmation entries to arrive and end up in their WAL
before committing the transactions.

Part-of #4847
