> OM support for ranged GET request for a specified part
> ------------------------------------------------------
>
> Key: HDDS-11699
> URL: https://issues.apache.org/jira/browse/HDDS-11699
> Project: Apache Ozone
> Issue Type: Improvement
> Components: OM, s3gateway
> Reporter: Ivan Andika
> Priority: Major
>
> HDDS-9654 added support for ranged GET request for specified part. However,
> currently it's implemented by filtering the OmKeyInfoLocation based on the
> partNumber in client side (RpcClient). Therefore, for a large MPU key (few
> hundred GBs with many parts), it still requires OM to send the whole
> List<OmKeyLocationInfo> for every S3 part GET request.
> We can implement the filter from the OM side (server side) to reduce the
> network overhead.
> Note: This change will require some additional communication protocol between
> S3G and OM. Therefore, it's most likely that we need to add a new
> OzoneManagerVersion to preserve compatibility.
