Bharat Viswanadham updated HDDS-712:
------------------------------------
Issue Type: Sub-task (was: Task)
Parent: HDDS-434
> Use x-amz-storage-class to specify replication type and replication factor
> --------------------------------------------------------------------------

> Key: HDDS-712

> This has been a comment in the Jira in HDDS-693 from
> @DefaultValue("STAND_ALONE") @QueryParam("replicationType")
> Just an opportunistic comment. Not part of this patch, this query param will
> not be sent by S3 hence this will always default to Stand_Alone. At some
> point we need to move to RATIS, Perhaps we have to read this via
> x-amz-storage-class.
> *I propose below solution for this:*
> Currently, in code we take query params replicationType and replicationFactor
> and default them to Stand alone and 1. But these query params cannot be
> passed from aws cli.
> We want to use x-amz-storage-class header and pass the values. By default for
> S3 If you don't specify this it defaults to Standard. So, in Ozone over S3
> also, as we want to default to Ratis and replication factor three by default.
> We can use the mapping Standard to RATIS and REDUCED_REDUNDANCY to Stand
> alone.
>
> There are 2 more values
> STANDARD_IA and ONEZONE_IA these need to be considered later how we want to
> use them. Intially we are considering to use Standard and Reduced_Redundancy.
