> 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
