[jira] [Created] (OAK-9063) Use a custom metadata property to manage lastModified in AzureDataStore

Amit Jain created OAK-9063:
------------------------------

             Summary: Use a custom metadata property to manage lastModified in AzureDataStore
                 Key: OAK-9063
                 URL: https://issues.apache.org/jira/browse/OAK-9063
             Project: Jackrabbit Oak
          Issue Type: Improvement
          Components: blob-cloud-azure
            Reporter: Amit Jain
            Assignee: Amit Jain


Currently, the lastModified property managed by azure is used but then to update the timestamp a copy operation is performed in the blob to itself. Besides inefficient, this operation sometimes causes problems if the copy operation is perfomed just after a blob wrrite in a parallel thread.

This issue changes the behaviour to manage the timestamp through a custom metadata property. While retrieving a fallback to azure managed timestamp is to bee used in case the metadata property is not available.
