> Create datanode API to verify the existence of groups of blocks

> Key: HDDS-12593
> URL: https://issues.apache.org/jira/browse/HDDS-12593
> Project: Apache Ozone
> Issue Type: Sub-task
> Reporter: Ethan Rose
> Assignee: Sarveksha Yeshavantha Raju
> Priority: Major
>
> In order to implement the block metadata existence check for replicas, we
> could use existing datanode APIs like {{listBlock}} or {{getBlock}}, but
> these are not optimal for the use case. It would be more efficient to add a
> new datanode API that takes a list of blocks from any container, and returns
> one result indicating whether each block and/or container is present on that
> node. This would allow the check to batch calls to datanodes for faster
> processing, and reduce the amount of unused metadata transmitted.
