Core Storage

Add a Configurable TTL to Control How Long a Blob Remains in the Storage After Async Key Generation dev admin

After the asynchronous blob digest computation, the blob's key is changed to its digest by creating a new blob and deleting the old one. It could be a problem if a process is started as soon as the original blob is saved to the final S3 storage.

We can now control with a TTL parameter how long the binary will remain in the storage before being removed by the async digest computation. It can be configured through:

  <require>org.nuxeo.ecm.core.blob.BlobManager</require>
  <extension target="org.nuxeo.runtime.ConfigurationService" point="configuration">
    <property name="nuxeo.blobmanager.delete.delay">2h</property>
  </extension>

The default is one hour.

More Reliable Bulk Action to Set Blob Length Into S3 dev admin

A new bulk action s3SetBlobLength is provided to asynchronously set the blob length into S3. This new bulk action supersedes the one previously introduced (s3SetContentLength).

The s3SetBlobLength bulk action is not activated by default this needs to be done explicitly from nuxeo.conf with:

binarymanager.bulk.s3SetBlobLength.enabled=true

The number of partitions (maximum concurrency at cluster level) and the concurrency (per worker node) can be tuned with:

binarymanager.bulk.s3SetBlobLength.partitions=4
binarymanager.bulk.s3SetBlobLength.concurrency=2

The action will process all blobs of a document unless an XPath filter is provided. The force flag will always fetch the length from s3 and the document will be updated if the length is different.

Here is an example of invocation only on the main blob (file:content) with the force flag and for all document of type File:

curl -v -X POST -H "Content-Type: application/json" "localhost:8080/nuxeo/api/v1/search/bulk/s3SetBlobLength?query=SELECT%20*%20FROM%20File" -u Administrator:Administrator -d '{"force": true, "xpath": "content"}'

Miscellaneous

Cleanup Temporary Folder at Startup admin

It is now possible to automatically clean the temporary folder at Nuxeo Server startup (to reduce storage space and avoid folder saturation).

To enable this feature and so delete the temporary folder at startup, you have to add this property to your nuxeo.conf:

nuxeo.startup.clean.tmp.dir=true
