MySQL 5.7: Enhanced Multi-threaded slaves
Employee +1 Vote Up -0Vote Down

Introduction

Re-applying binary logs generated from highly concurrent master on the slave has always been an area of focus. It is important for various reasons. First, in real-time systems, it becomes extremely important for the slave to keep up with the master. This can only be guaranteed if the slaves’ performance in reapplying the transactions from the binary log is similar (or at-least comparable) to that of master, which is accepting queries directly from multiple clients. Second, in synchronous replication scenarios, having a fast slaves, aids in reducing the response times as seen by the clients to the master. This can be made possible by applying transactions from the binary log in parallel. However if left uncontrolled, a simple round-robin multi-threaded applying will lead to inconsistency and the slave will no longer be the exact replica of the leader.

MySQL Cluster Asynchronous Replication – conflict detection & resolution
Employee +3 Vote Up -0Vote Down

I was rooting through past blog entries and I stumbled accross a draft post on setting up multi-master (update anywhere) asynchronous replication for MySQL Cluster. The post never quite got finished and published and while the material is now 4 years old it may still be helpfull to some and so I’m posting it now. Note that a lot has happened with MySQL Cluster in the last 4 years and in this area, the most notable change has been the Enhanced conflict resolution with MySQL Cluster active-active replication feature introduced in MySQL Cluster 7.2 and if you’re only dealing with a pair of Clusters, that’s your best option as it removed the need for you

The main bottleneck to most expansion is the database server and in many modern environments that replication is based around MySQL.  Application servers are easy to add on to the front-end of your environment.
