Bolke de Bruin created ATLAS-3368:
-------------------------------------
Summary: Very slow creation of entities with referred entities
without relationshipDef
Key: ATLAS-3368
URL: https://issues.apache.org/jira/browse/ATLAS-3368
Project: Atlas
Issue Type: Bug
Affects Versions: 2.0.0
Reporter: Bolke de Bruin
If an entity is created that has a definition with a reference to a non built
in type, e.g.
{code:java}
,{
"name" : "server",
"typeName" : "server",
"isOptional" : false,
"cardinality" : "SINGLE",
"valuesMinCount" : 1,
"valuesMaxCount" : 1,
"isUnique" : false,
"isIndexable" : true
}{code}
It will trigger a legacy code path in EntityGraphMapper. This path can take
excessive amounts of time:

{code}
Notice the 5 second(!) jump between the last two log lines. At a minimum the
log about triggering the legacy code path should be at WARN level and extended
with a suggestion to update the definition for better performance.
