Description

Background

Atlas administrators my want to export all data of a type. This may be needed in scenario where it may be necessary to move data to a different cluster.

Suggested Approach

Within AtlasExportRequest, support additional parameter that is a list of types. Additional option type say forType will help with identifying what is specified.

Processes this list as starting entity within ExportService.

Example:

{ 
"itemsToExport": [ 
  { "typeName": "hive_db,hdfs_path,hbase_namespace,hbase_table" } 
], 
"options": {  
  "fetchType": "FULL", 
  "matchType": "forType"
    } 
}
