Sitecore Cache Key Indexing - What is it?

Sitecore continuously introduces new concepts and mechanisms. Many developers easily miss to fully appreciate the advantages of these hidden features until they accidentally come across them. This blog post focuses on Cache key indexing, a discovery I made while investigating cache optimization techniques.

Premise

If you have a website or a multi-site that is of considerable size, such as having numerous articles or a vast directory of individuals from your company, incorporating a variety of components with distinct templates, languages, and versions can be beneficial. Additionally, introducing elements that are constantly changing, copied, or deleted is a common practice. 

If you are using Azure and find this scenario relatable, utilizing cache key indexing can potentially address any performance issues that your site may encounter.

What is Cache key indexing?

Cache key indexing offers a valuable solution in optimizing the performance of operations on a sizable cache. This technique proves especially beneficial in extensive systems where items undergo frequent renaming, moving, copying, and deletion. The feature of cache key indexing is accessible for the following caches:

  • Access Result cache
  • Item cache
  • Item paths cache
  • Paths cache

Steps to set up Cache key indexing

To enable cache key indexing on the Content Delivery and Standalone roles, create a patch file and set all cache key indexing settings to true.:

<configuration

    xmlns:patch="http://www.sitecore.net/xmlconfig/" 

    xmlns:set="http://www.sitecore.net/xmlconfig/set/">

    <sitecore>

        <settings>

            <setting name="Caching.CacheKeyIndexingEnabled.AccessResultCache" set:value="true"/>

            <setting name="Caching.CacheKeyIndexingEnabled.ItemCache" set:value="true"/>

            <setting name="Caching.CacheKeyIndexingEnabled.ItemPathsCache" set:value="true"/>

            <setting name="Caching.CacheKeyIndexingEnabled.PathCache" set:value="true"/>

        </settings>

    </sitecore>

</configuration>

Once the testing phase is complete, proceed to transfer the system to your production environment. If everything goes smoothly, you will observe a noticeable enhancement.

Hope it helps you!!

Sitecore PowerShell Script to create all language versions for an item from en version

  We have lots of media items and our business wants to copy the data from en version of media item to all other language versions defined in System/Languages. This ensures that media is available in all the languages. So, we created the below powershell script to achieve the same -  #Get all language versions defined in System/Languages $languages = Get-ChildItem /sitecore/System/Languages -recurse | Select $_.name | Where-Object {$_.name -ne "en"} | Select Name #Ensuring correct items are updated by comparing the template ID  $items = Get-ChildItem -Path "/sitecore/media library/MyProjects" -Recurse | Where-Object {'<media item template id>' -contains $_.TemplateID} #Bulk update context to improve performance New-UsingBlock (New-Object Sitecore.Data.BulkUpdateContext) { foreach($item in $items){    foreach($language in $languages){ $languageVersion = Get-Item -Path $item.Paths.Path -Language $language.Name #Check if language versi...

Make Sitecore instance faster using Roslyn Compiler

When we install the Sitecore instance on local, the first load is slow. After each code deploy also, it takes a while for the Sitecore instance to load and experience editor to come up. For us, the load time for Sitecore instance on local machines was around 4 minutes. We started looking for ways to minimize it and found that if we update our Web.config to use Roslyn compiler and include the relevant Nugets into the project, our load times will improve. We followed the simple steps - Go to the Project you wish to add the NuGet package and right click the project and click 'Manage NuGet Packages'. Make sure your 'Package Source' is set to nuget.org and go to the 'Browse' Tab and search Microsoft.CodeDom.Providers.DotNetCompilerPlatform. Install whichever version you desire, make sure you note which version you installed. You can learn more about it  here . After installation, deploy your project, make sure the Microsoft.CodeDom.Providers.DotNetCompilerPlatform.d...

Experience of a first time Sitecore MVP

The Journey I have been working in Sitecore for almost 10 years now. When I was a beginner in Sitecore, I was highly impressed by the incredible community support. In fact, my initial Sitecore learning path was entirely based on community written blogs on Sitecore. During a discussion with my then technology lead Neeraj Gulia , he proposed the idea that I should start giving back to developer community whenever I get chance. Just like I have been helped by many developers via online blogs, stackoverflow etc., I should also try to help others. Fast forward a few years and I met  Nehemiah Jeyakumar  (now an MVP). He had a big archive of his technical notes in the form Sitecore blogs. I realized my first blog dont have to be perfect and it can be as simple as notes to a specific problem for reference in future. That's when I probably created my first blog post on Sitecore. At that time, I didn't knew about the Sitecore MVP program. Over the years, I gained more confidence to writ...

Clean Coding Principles in CSharp

A code shall be easy to read and understand. In this post, I am outlining basic principles  about clean coding after researching through expert recommended books, trainings and based on my experience. A common example to start with is a variable declaration like - int i  The above statement did not clarify the purpose of variable i. However,  the same variable can be declared as -  int pageNumber The moment we declared the variable as int pageNumber, our brain realized that the variable is going to store the value for number of pages. We have set the context in our brain now and it is ready to understand what the code is going to do next with these page numbers. This is one of the basic advantages of clean coding. Reasons for clean coding -  • Reading clean code is easier - Every code is revisited after certain amount of time either by the same or different developer who created it. In both the cases, if the code is unclean, its difficult to understand and u...
