Sitecore items mass delete through serialization

In one of the Sitecore application i worked, we had to sync large amount of data from XML, XML had several thousands of records, there was also a business rule in place which used to check certain conditions/fields before it can be inserted as item in Sitecore.

We performed several tests in local environment, before that utility can be executed in QA and other high end environment, but in this process, we have to go back and delete all existing imported items several times.

This was a time consuming process, as deleting several thousand items in Sitecore, can make your Sitecore instance slow, so, we used Sitecore Serialization to delete the items in bulk.

serialize

The Sitecore serialization functionality is designed to help teams of developers that
work on the same Sitecore solution to synchronize database changes between their
individual development environments, but is also valuable when a single developer
works on a solution.

Serialization allows you to serialize an entire Sitecore database or a series of items in
a database to text files. You can then use these text files to transfer this database or
series of items to another database or Sitecore solution.

This is particularly helpful when we use Sitecore Item buckets to structure all our content items.

Serialization option can be enabled from “Developer” ribbon.

In this example, I have created a folder called “Generic Items” and added few items under it.

serialize-s1

Follow the following steps to bulk delete the items:

  • Select the folder whose child items you want to delete, in this case, it’s “Generic Items” folder.
  • In next step, from “Developer” ribbon, click on “Serialize tree” link, this will serialize selected item and child items.
  • Serialization process will start and, it will create .item file for Generic Items folder and all child items under it.
  • Sitecore will store the .item files in data\serialization folder- in my case it’s Data\serialization\master\sitecore\content\Helix\Home\Test Eventsserialize-s2
  • Let’s assume we want to delete all items of “Generic Items” folder, delete the .item files from file system.
  • Once .items files are deleted, go back to Sitecore and from Developer ribbon click on “Revert tree” link.
  • Sitecore will start synching your items back from file system.Serialization-Sync
  • Once the process end, refresh your “Generic Items” folder, and you won’t find any child items there.
  • Sitecore serialization can delete several thousand of items in just few mins, which is way faster then manually deleting the items, which affects performance as well.

This can reduce your development and testing time, when working with large amount of data.

Please let me know if you have any questions, or want to share thoughts around this.

Happy learning 🙂
