Doing a search on metadata using jclouds

I wanted to do a search on my SWIFT storage using metadata of the objects.

For example, if all my objects have metadata of X-object-Meta-startTime: <value> My objective is to search for objects with startTime of, let say, 20.

It is not yet implemented in swift itself: https://blueprints.launchpad.net/swift/+spec/searchable-metadata

Is there such an API in jclouds instead? Is it possible? (I'm using jclouds to interface with swift)

Solution

  • jclouds cannot provide more than the underlying object store provides and Swift has not yet implemented this feature. You can call BlobStore.list and BlobStore.blobMetadata on each result. Alternatively you can create your own mapping in an external service like a database, e.g., H2 or MySQL. This corresponds to the second approach in the link you provided.
