[jira] [Commented] (ATLAS-2960) Custom attribute inside an Attibute Definition

["Madhan Neethiraj (JIRA)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/ATLAS-2960?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16684698#comment-16684698 ] 

Madhan Neethiraj commented on ATLAS-2960:
-----------------------------------------

[~myselfmayur] - the attribute definition structure you listed is of earlier version. Starting with Atlas version 0.8, attribute definition is captured by [AtlasStructDef.AtlasAttributeDef|https://github.com/apache/atlas/blob/master/intg/src/main/java/org/apache/atlas/model/typedef/AtlasStructDef.java#L257]; 'options' field in AtlasAttributeDef can be used to store additional details - like the ones you listed. This field was added in ATLAS-1314.

Here is the V2 equivalent of your attribute definition given in the description above:

{noformat}
{
  "name":        "resourceSetID",
  "typeName":    "int",
  "isOptional":  false,
  "cardinality": "SINGLE",
  "isIndexable": true,
  "options":     {
    "source": "{ \"name\":\"hdfs\", \"originalName\":\"ID\" }"
  }
}
{noformat}


Hope this helps.
