[jira] [Updated] (HDDS-710) Optimize the bits used to represent
Blocks
[ https://issues.apache.org/jira/browse/HDDS-710?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]
Arpit Agarwal updated HDDS-710:
-------------------------------
Target Version/s: (was: 0.5.0)
> Optimize the bits used to represent Blocks
> ------------------------------------------
>
> Key: HDDS-710
> URL: https://issues.apache.org/jira/browse/HDDS-710
> Project: Hadoop Distributed Data Store
> Issue Type: Improvement
> Components: Ozone Client
> Reporter: Arpit Agarwal
> Assignee: Arpit Agarwal
> Priority: Critical
>
> An immutable block is identified by the following:
> - Container ID
> - Local Block ID
> - BCS (Block Commit Sequence ID)
> All of these values are currently exposed to the client. Instead we can have a composite block ID that hides these details from the client. A first thought is a naive implementation that generates a 192-bit (3x64-bit) block ID.
> Proposed by [~anu] in HDDS-676.
