             Summary: Data Migration: Import: Infer Types that Store Edge Ids
                 Key: ATLAS-2637
                 URL: https://issues.apache.org/jira/browse/ATLAS-2637
             Project: Atlas
          Issue Type: Improvement
          Components:  atlas-core
    Affects Versions: trunk
            Reporter: Ashutosh Mestry
            Assignee: Ashutosh Mestry
             Fix For: trunk


*Background*

Existing implementation of _Data Migration_ needs end user to specify properties of types that need post processing.

Post processing is essentially replacing the stored edge ids with the ones in the newly migrated database.

This is error prone, where the creator of types may not be aware of this, and hence may forget to specify the type and property during migration. This will result in entities of the type being unusable.

*Solution*

Infer the types and the properties in following way:
 * Navigating through all the types in type registry.
 * Find attributes that have arrays with array elements as object ids.

Pass these type-properties map to the migration process.

This will eliminate the need for letting user specify these properties.
