From mboxrd@z Thu Jan 1 00:00:00 1970 Return-Path: From: Vladislav Shpilevoy Subject: [PATCH 0/8] box.ctl.promote Date: Wed, 8 Aug 2018 01:03:43 +0300 Message-Id: To: tarantool-patches@freelists.org Cc: vdavydov.dev@gmail.com List-ID: Replicaset master promotion is a procedure of atomic making one slave be a new master, and an old master be a slave in a fullmesh master-slave replicaset. The promotion follows the protocol described in details in the corresponding RFC. Shortly, the protocol collects a quorum of instances who approves the promotion, syncs data with the old master and demotes it. The patchset consists of several preparation commits with the most important one describing the promotion protocol in details. The last two patches are the promotion itself and its garbage collection implementation.
