S3 Blob Storage: Adding Depth-Based Prefixes to Object Names

It is now possible, using the subDirsDepth configuration property for the blob store, to store objects in S3 using nested subdirectories to avoid having all objects in a flat hierarchy. For instance with a depth of 2 the object d41d8cd98f00b204e9800998ecf8427e will be stored as d4/1d/d41d8cd98f00b204e9800998ecf8427e.

Example XML configuration:

    <blobprovider name="...">
      <class>org.nuxeo.ecm.blob.s3.S3BlobProvider</class>
      ...
      <property name="subDirsDepth">2</property>
    </blobprovider>

If XML configuration is not used, and if all S3 blob providers can have the same value for this configuration property, a nuxeo.conf property may be used:

nuxeo.s3storage.subDirsDepth=2

Using a depth of 0 gives the standard behavior of storing everything flat.

Allow Configuration of Repository/Directory Indexes to Add, Even After Initial Creation

It is now possible to add MongoDB indexes using a contribution.

You can contribute indexes to be created at Nuxeo startup. Nuxeo supports these types of index: ascending, descending, and none to disable the index.

Contribute the XML below to make a property indexed:

<component name="my.component.name">
  <extension target="org.nuxeo.ecm.core.schema.TypeService" point="schema">
    <property schema="SCHEMA" name="PROPERTY" indexOrder="ascending" />
    <property schema="SCHEMA" name="PROPERTY" indexOrder="descending" />
  </extension>
</component>

Major Bug Fixes

Set Filename on Audio File Thumbnail Blob

Previously, the audio file thumbnail blobs were set without a filename which could break the UI if the CloudFront integration is enabled.

As we now set a filename to the audio thumbnail blob, the CloudFront integration doesn't break with audio thumbnails.

Bulk Command Scroller Should Be Aligned on the Underlying Page Provider
