S3 support

[030]

We have existing Alfresco environments. We are planning to migrate to S3. Does the plugin support this scenario as well?

[AFaust]

It does not (yet). Adding S3 support has been on my (bucket) list for a while, but so far I have not had the time / this addon did not have the priority over other addons to let me focus on that feature.

@AFaust Could you indicate what code could be adjusted to implement this? Perhaps I could implement it with some help.

[AFaust]

It is not so much "adjusting" as implementing anew by integrating additional libraries. As a summary, it would entail:

• implementing a terminal store like FileContentStore, with its reader and writer components
• use of the AWS SDK for Java or any better suited library (e.g. old projects like alfresco-cloud-store used jets3t)
• definition of a store template compliant with naming conventions, so the configuration mechanism of this addon supports the store (e.g. standard file store template)
• test, test, test

Issues / features that I have had on my list to check and possibly support are:

• support EC2 instance level IAM roles for S3 access, if Alfresco itself runs in AWS
• support of (mountable / externally resolveable) secrets
• (tangentially related) alternative deduplication approaches / deduplication without reliance on content URL structure to support the deduplicating facade store with S3 (and other content-address storage solutions)
