gardenia opened a new pull request, #9363:
URL: https://github.com/apache/ozone/pull/9363
Please describe your PR in detail:
In OzoneManagerStateMachine when certain write requests complete
successfully a summary of that request will be written to a new rocksdb
"ledger" table named CompletedRequestInfo
The current CompletedRequestInfo schema is minimal:
```
/**
* CompletedRequestInfo table entry
*/
message CompletedRequestInfo {
optional int64 trxLogIndex = 1;
required Type cmdType = 2; // Type of the command
optional string volumeName = 3;
optional string bucketName = 4;
optional string keyName = 5;
optional uint64 creationTime = 6;
optional CreateKeyOperationArgs createKeyArgs = 7;
optional RenameKeyOperationArgs renameKeyArgs = 8;
optional DeleteKeyOperationArgs deleteKeyArgs = 9;
optional CommitKeyOperationArgs commitKeyArgs = 10;
optional CreateDirectoryOperationArgs createDirectoryArgs = 11;
optional CreateFileOperationArgs createFileArgs = 12;
}
```
The use of "optional" for the arguments was based on feedback from the
community call where @errose28 made the point that the previous sketch of a
schema (using a freeform Map<String, String>) did not jibe well with schema
management and this optional pattern had been used in other places to get
around that.
This change adds the protobufs and entity class to store the completed event
info (with the intent that a consumer can use that data to generate event
notifications about changes on the filesystem)
