The last Coherence SIG at Oracle’s office in midtown had three topics — the last of which was an update on the Coherence Incubator. If you’re new to Coherence, the Incubator is home to a library of frequently used design patterns for Coherence clusters as well as experimental functionality which may or may not enter the product.

All design patterns depend on the Commons project which holds common implementation code. The Command Pattern is the most fundamental of these patterns, and the foundation on which all others are built. Its main idea is that instead of using Coherence’s synchronous EntryProcessors, commands can be run asynchronously using this design.

From what I understood, the latest incubator developments were in the Push Replication pattern which allows for data to be published to remote devices, including other Coherence clusters. The published data can be batched and even filtered such that only data of your choosing is replicated.

To get more details and to see what’s cooking in the labs, here’s where to get started.
