 ## Implementation Details
 
-### Message brokers
-The multi-site plugin adopts an event-sourcing pattern and is based on an
-external message broker. The current implementation uses Apache Kafka.
-It is, however, potentially extensible to others, like RabbitMQ or NATS.
+### Multi-site libModule
+As mentioned earlier there are different components behind the overarching architecture
+of this solution of a distributed multi-site gerrit installation, each one fulfilling
+a specific goal. However, whilst the goal of each component is well-defined, the
+mechanics on how each single component achieves that goal is not: the choice of which
+specific message broker or which Ref-DB to use can depend on different factors,
+such as scalability, maintainability, business standards and costs, to name a few.
+
+For this reason the multi-site component is designed to be explicitly agnostic to
+specific choices of brokers and Global Ref-DB implementations, and it does
+not care how they, specifically, fulfill their task.
+
+Instead, this component takes on only two responsibilities:
+
+* Wrapping the GitRepositoryManager so that every interaction with git can be
+verified by the Global Ref-DB plugin.
+
+* Exposing DynamicItem bindings onto which concrete _Broker_ and a _Global Ref-DB_
+plugins can register their specific implementations.
+When no such plugins are installed, then the initial binding points to no-ops.
+
+* Detect out-of-sync refs across multiple gerrit sites:
+Each change attempting to mutate a ref will be checked against the Ref-DB to
+guarantee that each node has an up-to-date view of the repository state.
+
+### Message brokers plugin
+Each gerrit node in the cluster needs to be informed and inform all other nodes
+about fundamental events, such as indexing of new changes, cache evictions and
+stream events. This component will provide a specific pub/sub broker implementation
+that is able to do so.
+
+When provided, the message broker plugin will override the dynamicItem binding exposed
+by the multi-site module with a specific implementation, such as Kafka, RabbitMQ, NATS, etc.
+
+#### Broker Noop implementation
+The default `Noop` implementation provided by the `Multi-site` libModule does nothing
+upon publishing and producing events. This is useful for setting up a test environment
+and allows multi-site library to be installed independently from any additional
+plugins or the existence of a specific broker installation.
+The Noop implementation can also be useful when there is no need for coordination
+with remote nodes, since it avoids maintaining an external broker altogether:
+for example, using the multi-site plugin purely for the purpose of replicating the Git
+repository to a disaster-recovery site and nothing else.
+
+### Global Ref-DB plugin
+Whilst the replication plugin allows the propagation of the Git repositories across
+sites and the broker plugin provides a mechanism to propagate events, the Global
+Ref-DB ensures correct alignment of refs of the multi-site nodes.
+
+It is the responsibility of this plugin to store atomically key/pairs of refs in
+order to allow the libModule to detect out-of-sync refs across multi sites.
+(aka split brain).  This is achieved by storing the most recent `sha` for each
+specific mutable `refs`, by the usage of some sort of atomic _Compare and Set_ operation.
+
+We mentioned earlier the [CAP theorem](https://en.wikipedia.org/wiki/CAP_theorem),
+which in a nutshell states that a distributed system can only provide two of these
+three properties: _Consistency_, _Availability_ and _Partition tolerance_: the Global
+Ref-DB helps achieving _Consistency_ and _Partition tolerance_ (thus sacrificing
+Availability).
+
+See [Prevent split brain thanks to Global Ref-DB](#prevent-split-brain-thanks-to-global-ref-db)
+For a thorough example on this.
+
+When provided, the Global Ref-DB plugin will override the dynamicItem binding
+exposed by the multi-site module with a specific implementation, such as Zoekeeper,
+etcd, MySQL, Mongo, etc.
+
+#### Global Ref-DB Noop implementation
+The default `Noop` implementation provided by the `Multi-site` libModule accepts
+any refs without checking for consistency. This is useful for setting up a test environment
+and allows multi-site library to be installed independently from any additional
+plugins or the existence of a specific Ref-DB installation.

-An implementation of the out-of-sync detection logic could be based on a central
-coordinator holding the _last known status_ of a _mutable ref_ (immutable refs won't
-have to be stored here). This would be, essentially, a DFS base `RefDatabase` or `DfsRefDatabase`.
