-----------------------------------------
Summary: Improve tag propagation performance using in-memory
traversal
Key: ATLAS-3563
URL: https://issues.apache.org/jira/browse/ATLAS-3563
Project: Atlas
Issue Type: Task
Components: atlas-core
Affects Versions: 2.0.0
Reporter: Sarath Subramanian
Assignee: Sarath Subramanian
Fix For: 2.1.0
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
