Christian R created ATLAS-1868:
----------------------------------
Summary: Highly inefficient DSL-queries
Key: ATLAS-1868
URL: https://issues.apache.org/jira/browse/ATLAS-1868
Project: Atlas
Issue Type: Bug
Components: atlas-core
Affects Versions: 0.7-incubating
Environment: linux, hbase + solr configuration.
Reporter: Christian R
The DSL query 'mytype where property.id = "id1"' appears to be rewritten as a
gremlin query that resembles:
g.V.has(typename, 'mytype'ยจ).as(x).out('property').has('id', 'id1').back('x')
On our system this query takes 6-7 minutes. The query
g.V.has('id', 'id1').in('property').has('typename', 'mytype')
takes 350 milliseconds.
Our graph:
g.V.count() = 1359151
We have atlas 0.7 installed. I've compiled the latest 0.9 code and looked at
the generated gremlin query as reported in the logs for the same DSL-query, and
I think 0.9 has the same performance issues. Unfortunately I don't have a big
graph on a 0.9 installation to test performance.
