Replication in distributed systems: Single leader / Master-Slave / Active-Passive

00:00-00:28 Introduction
00:28-00:57 Why do we need replication?
00:57-02:02 Replication implementation and challenges
02:02-04:35 Single-leader replication basics: clusters, replicas and leaders
04:35-04:44 Systems that use master-slave replication
04:44-06:09 Transferring changes to followers: sync vs. async vs. semi-sync
06:09-06:28 How fast is replication?
06:28-06:45 The benefits of synchronous replication
06:45-07:12 The disadvantages of synchronous replication
07:12-07:37 Semi-synchronous replication
07:37-08:17 Fully asynchronous replication
08:17-09:32 Adding new replicas to clusters (snapshots and binlogs)
09:32-10:44 Conclusions
