---------------------------------------
Summary: Use x-amz-storage-class to specify replication type and
replication factor
Key: HDDS-712
URL: https://issues.apache.org/jira/browse/HDDS-712
Project: Hadoop Distributed Data Store
Issue Type: Task
Reporter: Bharat Viswanadham
Assignee: Bharat Viswanadham
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.
