Assignee: Chen-Jheng Sing (was: Attila Doroszlai)
> Reduce copying in OMFileRequest.getDirectoryInfo
> ------------------------------------------------
>
> Key: HDDS-14172
> URL: https://issues.apache.org/jira/browse/HDDS-14172
> Project: Apache Ozone
> Issue Type: Sub-task
> Components: Ozone Manager
> Reporter: Attila Doroszlai
> Assignee: Chen-Jheng Sing
> Priority: Major
>
> {{OMFileRequest.getDirectoryInfo}} creates {{OmDirectoryInfo}} from
> {{OmKeyInfo}}, copying list of {{acls}}, map of {{metadata}} and {{tags}}.
> After HDDS-14151 we can skip copying by storing {{OmKeyInfo}}'s immutable
> collections directly.
> - Change {{OmKeyInfo#getAcls()}} to return {{ImmutableList}},
> - Add {{private OmDirectoryInfo.Builder(OmKeyInfo)}}, which should
> -- call {{super(keyInfo)}} to set inherited properties
> -- assign {{acls = AclListBuilder.of(keyInfo.getAcls())}}
> -- assign {{tags = MapBuilder.of(keyInfo.getTags())}}
> -- assign {{name = keyInfo.getFileName()}}, {{OzoneFSUtils.getFileName}} is
> no longer necessary
> -- set creation/modification time as is
> - Add {{public static OmDirectoryInfo of(OmKeyInfo)}}, and replace
> {{OMFileRequest.getDirectoryInfo}} implementation with a call to it.
