However, there are some noticeable differences that you need to take into account when setting up an Oak based AEM installation: What is different from Jackrabbit 2? Because Oak is designed to be backwards compatible with the JCR 1.0 standard, there will be almost no changes on the user level. Previous documents only contain immutable data, which means they only contain committed and merged revisions.Д¬luster node metadata Data about active and inactive cluster nodes is kept in the database in order to facilitate cluster operations.ДЄ typical AEM cluster setup with MongoDB storage:

Old data is moved when a certain threshold is met. However, it only deletes data if a cleanup is explicitly triggered. Previous documents MongoDB storage adds data to a document with every modification. The cluster node id where the revision was created п‚·Д«ranches Branches are supported, which allows client to stage multiple changes and make them visible with a single merge call. A counter to distinguish revisions created with the same timestamp 3. A timestamp derived from the system time of the machine it was generated on 2. A revision is basically a string that consists of three elements: 1.

It has several particularities: п‚·ДЇor each update (commit) of the content, a new revision is created. The repository tree is kept in one MongoDB database where each node is a separate document. Mongo Storage The MongoDB storage leverages MongoDB for sharding and clustering. This makes searching the repository very fast and avoids most cache misses for typical clients that access more than one related node per session.Д¬ompactness The formatting of records is optimized for size to reduce IO costs and to fit as much content in caches as possible. Locality Related records like a node and its immediate children are usually stored in the same segment. Each segment keeps a list of UUIDs of other referenced segments. In addition, segments can reference other content. Each segment is identified by a unique identifier (UUID) and contains a continuous subset of the content tree. They are immutable, which makes it easy to cache frequently accessed segments and reduce system errors that may corrupt the repository. Immutable Segments The content is stored in segments that can be up to 256KiB in size. There are several key design principles it was build around: п‚· Journals are used to track the latest state of the repository.

It stores the content as various types of records within larger segments. Tar Storage The Tar storage uses tar files. Currently, there are two storage implementations available in AEM6: Tar Storage and MongoDB Storage. Storage overview The Oak storage layer provides an abstraction layer for the actual storage of the content. It is also responsible for:Д¬ontaining commit hooks that implement JCR constraints In addition, non-Java implementations are now possible and part of the Oak JCR concept. Oak JCR The main objective of the Oak JCR is to transform JCR semantics into tree operations. Oak Core The Oak Core adds several layers to the storage layer: п‚·

Storage The purpose of the Storage layer is to: п‚· Support for many child nodes and Access Control Levels Multiple distributed cluster nodes for high availability It is the successor to Jackrabbit 2 and is used by AEM 6 as the default backend for its content repository, CRX.Дesign principles and goals Oak implements the JSR-283 (JCR 2.0) spec. Apache Jackrabbit Oak is an effort to implement a scalable and performant hierarchical content repository for use as the foundation of modern world-class web sites and other demanding content applications. The AEM platform in AEM 6 is based on Apache Jackrabbit Oak.
