Subject: [Tarantool-patches] [PATCH v6 3/3] box: start counting local space requests separately
Date: Tue,  7 Apr 2020 18:49:56 +0300	[thread overview]
Message-ID: <baae81ff0eefc6c511ed306c55955ec3b6c562bd.1586273440.git.sergepetrenko@tarantool.org> (raw)
In-Reply-To: <cover.1586273440.git.sergepetrenko@tarantool.org>

Sign local space requests with a zero instance id. This allows to split
local changes aside from the changes, which should be visible to the whole
cluster, and stop sending NOPs to replicas to follow local vclock.

Moreover, it fixes the following bug with local spaces and replication.
In a situation when there are a master and a replica set up, replica may
still write to local spaces even if it's read-only. Local space
operations used to promote instance's lsn before this patch. Eventually,
master would have vclock {1:x} and replica'd have vclock {1:x, 2:y},
where y > 0, due to local space requests performed by the replica.
If a snapshot happens on replica side, replica will delete it's .xlog
files prior to the snapshot, since no one replicates from it and thus it
doesn't have any registered GC consumers.
From this point, every attempt to configure replication from replica to
master will fail, since master will try to fetch records which account
for the difference in master's and replica's vclocks: {1:x} vs {1:x,2:y},
even though master will never need the rows in range {2:1} - {2:y},
since they'll be turned to NOPs during replication.

Starting from this patch, in the situation described above, replica's
clock will be {0:y, 1:x}, and, since local space requests are now not
replicated at all, master will be able to follow replica, turning the
configuration to master-master.

Closes #4114
