displayName
> Add support for Azure Blob Storage and Table Storage
> ----------------------------------------------------
>
> Key: NIFI-1833
> URL: https://issues.apache.org/jira/browse/NIFI-1833
> Project: Apache NiFi
> Issue Type: Improvement
> Components: Extensions
> Affects Versions: 0.6.1
> Reporter: Simon Elliston Ball
> Assignee: Jeff Storck
> Priority: Minor
> Fix For: 1.2.0
>
>
> It would be useful to have an Azure equivalent of the current S3 capability.
> Azure also provides a Table storage mechanism, providing simple key value
> storage. Since the Azure SDKs are Apache Licensed, this should be reasonably
> straightforward. A first cut is available as an addition to the existing
> azure bundle.
