DXA 2.0 introduction and future

DXA 2.0 is change in terms of compatibility and existing model and releases.
here is list of changes and features in this greatest and latest release of Digital Experience Accelerator.

• Trivident's DD4T and SDL DXA will merge to become a one product. it will allow to release it fast and compatible versions.
• Product Backlog will be made public to community.
• R2 - New Data Model 
• Clean Data Model comparable to existing. 
• Major changes in Caching, support of Donut caching.
• Introduction to Model service, which runs at Delivery Side & DXA app consumes it.
• Enhance performance using new tbbs and DXA resolver, As Expansion of linked components is now happens in Model Service
• Improvements in Publishing Pipeline.
• Extension points for CIL.net
• Developer can change/extend implementation.
•  Logging
• oAuth provider.
• ADF claim store provider etc

Architecture

Caching

• Make it all distributed or place only certain cache regions in distributed cache
• Provides output caching and view model caching
• New output caching supports dynamic entities as well, Implement via  annotation of classes using     new properties:
          [DxaOutputCache]
          [DxaNoOutputCache]
• You can cache fully built view and entity models
• Mark models as dynamic to avoid them cached.
• Support for Redis to support Distributed Cache.

Migration from existing DXA versions

• - DXA 1.x -> DXA 1.8 ->  DXA 2.x [.NET]
• - DXA 1.x -> DXA 1.8 ->  DD4T 2 ->  DXA 2.x [Java]

Caching in SDL Tridion Content Delivery System - Part 2

Configuring Cache

<logger name="com.tridion.cache" level="DEBUG">
<appender-ref ref="rollingCacheLog" />
 </logger>

Content Delivery caches its published content using its default implementation, which means that items are removed based on the "least-recently-used" policy (items that were least recently used are removed first) and using the dependency tracking feature (items are not removed if they depend on other items still in the cache). Only LRU policy is available.

Cache Invalidation Mechanism

- Cache Channel Service
- Apache MQ

Cache channel service has issues with Port allocation, CCS opens random ports sometime or required lots of ports to be opened for communication, so its least preferred way.

Another way is Apache MQ, its mostly used invalidation system, but install version as specified by SDL, because latest version does not work on it and cause lots of issues.

With DXA 2.0 SDL start offering Model service cache on the delivery side, which resolve the object and dependency, it also offer cache and its specified as follow.

Caching in SDL Tridion Content Delivery System - Part 1

SDL Content delivery has many different components and, caching happens at multiple levels. I am trying to explain different level of caching here.

- Server Side Cache (Delivery System)
- Client Side Cache (.net/java app)

By default, caching of published content is not enabled. You need to enable it in the cd_storage.config
