             Summary: Added 'isAppendOnPartialUpdate' option in ML model to attend updates
                 Key: ATLAS-3712
                 URL: https://issues.apache.org/jira/browse/ATLAS-3712
             Project: Atlas
          Issue Type: Improvement
          Components:  atlas-core
    Affects Versions: 3.0.0
            Reporter: Na Li
            Assignee: Na Li


Atlas adds a new feature to allow client to append attributes during partial-update operation in ATLAS-3700.

We need to add 'isAppendOnPartialUpdate' option in ML model at https://github.com/apache/atlas/blob/master/addons/models/4000-MachineLearning/4010-ml_model.json to append updates using this new feature.

Example:

{
    "name":        "metadata",
    "typeName":    "map<string,string>",
    "isIndexable": false,
    "isOptional":  true,
    "isUnique":    false,
    "options": \{
      "isAppendOnPartialUpdate": "true"         <-- add this option
    }
  }

The value specified for this attribute in partial-update API calls will be appended to existing value - if present. 

Full-update API calls will overwrite the value of the attribute, as it does currently; there is no change in full-update behavior.
