- KEY POINT: Applications communicate directly to the services they need to fulfil the aplication request and the application does not need to be topology aware as the SDK has that already. Single node type, services defined dynamically One node acts the same as 100, just the services are spread out in the cluster Query service accesses Index and Data to formulate response All query and document access is topology aware and dynamically scalable Develop with one node, deploy against multiple production nodes The Couchbase SDK handles knowing about where in the cluster it needs to go to satisfy whatever the application is requesting, be I CRUD or cluster management.

- KEY POINT: EACH COUCHBASE NODE HAS THE SAME SOFTWARE AND THESE ARE THE COMPONENTS. WHETHER THEY TURN THEM ALL ON DEPENDS ON THEIR FUNCTIONAL AND SCALLING NEEDS. Data Node is the heart of the database. Everything interacts with this service to read and write data. It includes a high performance managed cache Index Nodes receive a DCP stream of all changes from the data nodes, but for the N1QL query execution flow are only accessed by the Query Service. Query Service – Holds no data, but accesses indexes on the Indexing Services as well as Views and Data on the Data Service. It exposes a REST API to interface with it and then communicates with the other service as needed to Cluster Manager – Contains the WebUI, REST API and Performs the background tasks of the cluster such as cluster orchestration.
- Key Points: MDS provides the ability for cluster administrator to separate the various workloads and tailor the cluster architecture for the application’s scalability and performance needs. This while providing the functionality needed by by the application. Pictured is a possible architecture where all the cluster has been split with the Query and Index Service on different nodes of the cluster. This allows you to not only isolate the workload, but you could have the nodes with the other services with different server configs. For example, the query service needs CPU and RAM and has no storage, but the Index service needs Ram and fast disks. So you could configure these nodes different from the Data Service nodes to tailor performance even further. This is what allows Couchbase to scale with querying. The indexing and query services are eventually consistent by default, but in code can be made to fully

- KEY POINT: COUCHBASE ENABLES YOU TO EASILY MEET YOUR HA AND DR REQUIREMENTS WITH MEMORY TO MEMORY REPLICATION BETWEEN TO SEPARATE CLUSTERS. Cross–Data Center Replication to provide an easy yet powerful way to replicate data from one cluster to another for increased high availability, disaster recovery, and geographic load balancing. In Couchbase Server 4.0, we’ve added filtering capabilities to Cross–Data Center Replication (XDCR) in order to significantly reduce the amount of data replicated across data centers. - XDCR Filtering achieves this reduction by replicating only data relevant to the destination. - Couchbase customers no longer need to create many different buckets just to segment data for Cross–Data Center Replication.
