Bugs: ATLAS-3563
https://issues.apache.org/jira/browse/ATLAS-3563
Repository: atlas
Description
-------
Tag propagation uses gremlin query to find entities to which the tag has to be
propagated to.
Gremlin query is not scaling well for entities with large lineage (with many
depth). In-memory traversal seems to have improved performance significantly
since it avoids the overhead added by gremlin script engine initialization,
query execution time.
Performance improvement in tag propagation from 3004 ms to 180 ms is seen

Testing
-------
Manually validated tag propagation works.
* Add classification
* Block propagation
* Change Propagation direction
* Remove Classification
Thanks,
