------------------------------------
Summary: Implement OM read/write paths for bucket tagging with
audit and metrics
Key: HDDS-15510
URL: https://issues.apache.org/jira/browse/HDDS-15510
Project: Apache Ozone
Issue Type: Sub-task
Affects Versions: 2.2.0
Reporter: Gargi Jaiswal
Assignee: Gargi Jaiswal
Implement Ozone Manager support for storing and retrieving S3-style bucket tags
on {color:#00875a}{{OmBucketInfo}}{color}. *PUT* and *DELETE* are write
operations; *GET* is a read path via
{color:#00875a}{{OmMetadataReader}}{color}. Tags are stored on the source
bucket record in OM DB.
*Scope:*
* *Write path*
** {{{color:#00875a}S3PutBucketTaggingRequest.java{color}}} — set tags on
bucket, update modification time
** {{{color:#00875a}S3DeleteBucketTaggingRequest.java{color}}} — clear tags
** Register in {color:#de350b}{{OzoneManagerRatisUtils.java}}{color}
* *Read path*
** {{{color:#de350b}OmMetadataReader.getBucketTagging(){color}}} — read tags
from *{{OmBucketInfo}}*
** {{{color:#00875a}OzoneManagerRequestHandler.getBucketTagging(){color}}}
** {{{color:#00875a}OzoneManager.getBucketTagging(){color}}}
* *Cross-cutting*
** *{{OMAction}} —* {{{}PUT_BUCKET_TAGGING{}}}, {{{}GET_BUCKET_TAGGING{}}},
{{DELETE_BUCKET_TAGGING}}
** {{OMAuditLogger}} mapping
** {{OMMetrics}} / {{OmMetadataReaderMetrics}} counters
** {{IOmMetadataReader}} interface
* OM unit tests
** Put tagging on bucket
** Get tagging (empty → tags present)
** Delete tagging
** Put overwrites existing tags (replace semantics)
** Bucket not found errors
