      Orphan versions cleanup is now disabled by default, and can be re-enabled (if its performance is acceptable) by doing:

        <require>org.nuxeo.ecm.core.orphanVersionsCleanup</require>
        <extension point="listener" target="org.nuxeo.ecm.core.event.EventServiceComponent">
          <listener name="orphanVersionsCleanup" enabled="true" />
        </extension>

      Description

      The listener orphanVersionsCleanup introduced by NXP-14187 takes too much resources when there are lots of data.

      1. orphanVersionsCleanup script can be called manually up to 8.10
      2. from 8.10 HF01 +, it is possible to enable it through a contribution:
        https://doc.nuxeo.com/810/nxdoc/hotfixes-installation-notes-for-nuxeo-platform-lts-2016/#orphan-versions-cleanup
      3. in 9.10 it is scheduled by default

      This leads to performance impact on big deployments with hundreds of millions of documents.

      The doCleanupOrphanVersions method fetches all the document versions and working copies UUIDs:
      https://github.com/nuxeo/nuxeo/blob/release-10.1/nuxeo-core/nuxeo-core/src/main/java/org/nuxeo/ecm/core/CoreService.java#L173

      This should be for instance dealt through a batch process thus limiting the resources usage and notably RAM.

      —> deactivate this listener by default.

      The ticket NXP-27139 covers work to improve the cleanup algorithm to scale.
