> Broadcasting cache
> ------------------
>
> Key: OAK-2843
> URL: https://issues.apache.org/jira/browse/OAK-2843
> Project: Jackrabbit Oak
> Issue Type: Improvement
> Components: mongomk
> Reporter: Thomas Mueller
> Assignee: Thomas Mueller
> Fix For: 1.3.11
>
>
> In a cluster environment, we could speed up reading if the cache(s) broadcast
> data to other instances. This would avoid bottlenecks at the storage layer
> (MongoDB, RDBMs).
> The configuration metadata (IP addresses and ports of where to send data to,
> a unique identifier of the repository and the cluster nodes, possibly
> encryption key) rarely changes and can be stored in the same place as we
> store cluster metadata (cluster info collection). That way, in many cases no
> manual configuration is needed. We could use TCP/IP and / or UDP.
