Orchestrator 1.0.5: refactoring masters, multi-master replication

August 6, 2014

Outbrain's orchestrator Version 1.0.5 is released.

Quick links: Orchestrator Manual, FAQ, Downloads

Orchestrator now supports refactoring of masters via master-master topologies. It now allows promoting slaves as co-masters and detachment of instances from a co-master topology, effectively allowing for replacing an active master.

Like this

Drag a master:

orchestator-cm-simple-drag-master-01

Onto one of its slaves:

orchestator-cm-simple-drag-master-02

Making both co-masters:

orchestator-cm-simple-dropped-master

orchestator-cm-co-masters

You now have a multi-master topology. You may move slaves around between the masters. Or, if you like, detach the newly promoted co-master from its original master:

orchestator-cm-simple-detach-slave-01

Now it becomes the single master:

orchestator-cm-new-master

Refactor as you will:

orchestator-cm-simple-new

Orchestrator is released as open source under the Apache 2.0 license and is available at: https://github.com/outbrain/orchestrator
