What's New in LTS 2021.35 / LTS 2021-HF35

Clean Up Orphan Binaries After Document Removal, Blob Property Edition and Dispatch

Whenever a:

  • document is removed
  • document blob property is edited
  • document blob property is dispatched to another blob provider
    a domain event referencing the related blob(s) is fired and a record is written to the "source/blob" stream for each blob candidate for deletion.

This stream is consumed asynchronously and the blob is eventually deleted if it is not referenced by any other documents.

Note that, this process is only available on instances working with:

  • repositories having the "ecm:blobKeys" capability (introduced by NXP-29516 (i.e. MongoDB)
  • blob providers extending BlobStoreBlobProvider such as S3BlobProvider and LocalBlobProvider

In case of multi-repository deployment with a custom Blob Dispatcher configuration, the Nuxeo platform cannot ascertain that each repository has its own different binary store path and binaries referenced in another repository may be deleted (see documentation. In that case, it is recommended to disable this feature with NXP-31794.

Delete Orphan Workflows and Tasks

Orphaned workfows can be deleted daily along with wokflows in state "done" or "canceled'. A new management endpoint is available to GC orphaned, done or canceled workflows on demand.

The DocumentRoutingWorkflowInstancesCleanup listener (triggered daily), which removes the workflow in state done or canceled, has been reimplemented to leverage BAF. Note that the tasks related to a removed workflow are also removed.

By setting the nuxeo.routing.cleanup.workflow.instances.orphan conf property to true (false by default), the DocumentRoutingWorkflowInstancesCleanup listener will also remove orphan workflows daily.

A new management rest API endpoint is also available to perform a workflow garbage collection on demand. See documentation.
