Tejaskriya opened a new pull request, #6976: URL: https://github.com/apache/ozone/pull/6976
## What changes were proposed in this pull request? RocksDB stores data in key-value pairs. The value itself may have some kind of key-value structure. Currently, `ozone debug ldb scan` command shows the full value for each record being displayed. This could be very verbose and include information that is not needed for the use case. Having a --fields option which filters the fields being displayed for each record will help to get concise output. For example, if a value has many fields like [name, location->[address, DN, IP], version, lastUpdateTime] , using the option "--fields=name,location.address,version" will display only (name, address in location and version) in the output. ## What is the link to the Apache JIRA https://issues.apache.org/jira/browse/HDDS-11190 ## How was this patch tested? Tested manually in docker cluster: ``` sh-4.2$ ozone debug ldb --db=/data/metadata/om.db scan --cf=fileTable --fields=volumeName,bucketName,keyName,keyLocationVersions.locationVersionMap { "/-9223372036854775040/-9223372036854774528/-9223372036854771967/k1": { "bucketName" : "bb1", "volumeName" : "vol1", "keyName" : "k1", "keyLocationVersions.locationVersionMap" : [ { "locationVersionMap" : { "0" : [ { "blockID" : { "containerBlockID" : { "containerID" : 1, "localID" : 113750153625600003 }, "blockCommitSequenceId" : 10 }, "length" : 3, "offset" : 0, "createVersion" : 0, "partNumber" : 0 } ] } } ] } , "/-9223372036854775040/-9223372036854774528/-9223372036854774528/k1": { "bucketName" : "bb1", "volumeName" : "vol1", "keyName" : "k1", "keyLocationVersions.locationVersionMap" : [ { "locationVersionMap" : { "0" : [ { "blockID" : { "containerBlockID" : { "containerID" : 1, "localID" : 113750153625600001 }, "blockCommitSequenceId" : 2 }, "length" : 3, "offset" : 0, "createVersion" : 0, "partNumber" : 0 } ] } } ] } ``` -- This is an automated message from the Apache Git Service.
