Description

Following work done in JAMES-2563 we want to introduce a health-check for object-storage.

Add a `long countBlob()` public method to the ObjectStorageBlobsDAO class.

In your ObjectStoragetHealthCheck call this method:

• If a count is returned then swift is healthy
• If an exception is encountered then swift is unhealthy.

Write tests on top of a `pausable` swift container in `server/blob/blob-objectstorage`.

Bind this health check in `server/container/guice/blob-objectstorage-guice/src/main/java/org/apache/james/modules/objectstorage/ObjectStorageBlobStoreModule.java`
