---------------------------------------
Summary: Perf and stability improvements to DSL search to search
only by typeNames
Key: ATLAS-1403
URL: https://issues.apache.org/jira/browse/ATLAS-1403
Project: Atlas
Issue Type: Bug
Affects Versions: 0.7-incubating
Reporter: Suma Shivaprasad
Assignee: Suma Shivaprasad
Fix For: 0.7.1-incubating, 0.8-incubating
Currently DSL uses a filll function to merge results by typeName and
superTypeName and loads the reskuting vertices in memory. This causes
significant memory usage and ATLAS server spends lot of time doing GC instead
of useful work resulting in OOO sometimes ( when GC is not able to recover and
search queries are run in parallel)
The proposal is to replace this with typname checks along by finding all the
subtypes for a given type and using an IN clause in the filter.
For eg:
Query = Person where (birthday < "1950-01-01T02:35:58.440Z") limit 40 offset 0
Optimized query
Gremlin Query = L:{g.V.has("__typeName", T.in,
['Person','Manager']).and(_().has("Person.birthday", T.lt, -631142641560))
[0..<40].toList()}
