[GitHub] [incubator-doris] morningman opened a new pull request #2571: [Tag system] Introduce ReplicaAllocation and Backend TagSet

morningman opened a new pull request #2571: [Tag system] Introduce ReplicaAllocation and Backend TagSet
URL: https://github.com/apache/incubator-doris/pull/2571
 
 
   This CL introduces the `ReplicaAllocation` class.
   `ReplicaAllocation` is used to identify the distribution information of the replica, and the
    distribution information is represented by a set of tags.
   `ReplicaAllocation` is stored in `PartitionInfo` and replaces the previous `idToReplicationNum`
   object. This conversion operation is performed when the FE replays the metadata.
   
   At the same time, the `Backend` object will inherit from the `Resource` abstract class and
   start to have the `TagSet` attribute. The `TagSet` attribute is currently generated by the cluster
    name of the Backend. This conversion operation is also performed when the FE replays the
    metadata.
   
   To maintain compatibility and minimize the impact on existing metadata. We currently retain all
    cluster information. The new `ReplicaAllocation` and `TagSet` classes are only converted and
    stored.
   
   We will start using `ReplicaAllocation` and `TagSet` in the next commit.
   
   I added a proc `"/ tags"` to show all tags and the corresponding resource ids.
   I also added an http action `/metacheck?type=replica_allocation` to check if the 
   `ReplicaAllocation` and `TagSet` were converted correctly after the upgrade.
