About

=====

Metronome is scheduling tool for ordering event over members in consul cluster.

When event is sent to consul cluster, Each server in the cluster will start processing parallel, But an order of processing over multiple servers is important when create system that is structured from multiple servers.

For example, all database servers should have been configured before application server, and load balancer will accept request from client after all inner servers have been ready.

Metronome can manage these order with configuration file and event queuing system on consul KVS.

![Metronome architecture](https://raw.githubusercontent.com/wiki/cloudconductor/metronome/en/diagram.png)

First, when a consul has received event, the event handler on consul trigger metronome with push subcommand, and metronome enqueue received event to event queue on consul KVS.

Metronome is polling event from event queue and dispatch it to the progress task queue with filtering condition that contains service and tag that specified by configuration file.

Each server fetch head task of progress task queue and execute operation if qualified its filter, other servers wait for finishing these operation as it fetch first task.
