Component, Query & Data
Affected feature:
ArangoDb instance
AQL query (if applicable):
for u in union([],[])
collect test = u.v into g
return Distinct {
Test: test,
Prop1: MIN(g[*].u.someProp),
Prop2: MAX(g[*].u.someProp)
}
AQL explain and/or profile (if applicable):
Execution plan:
Id NodeType Est. Comment
1 SingletonNode 1 * ROOT
2 CalculationNode 1 - LET #7 = [ ] /* json expression */ /* const assignment */
3 EnumerateListNode 0 - FOR u IN #7 /* list iteration */
4 CalculationNode 0 - LET #9 = u.`v` /* attribute expression */
9 SortNode 0 - SORT #9 ASC /* sorting strategy: standard */
5 CollectNode 0 - COLLECT test = #9 INTO g KEEP u /* sorted */
6 CalculationNode 0 - LET #11 = { "Test" : test, "Prop1" : MIN(g[*].`u`.`someProp`), "Prop2" : MAX(g[*].`u`.`someProp`) } /* simple expression */
7 CollectNode 0 - COLLECT #13 = #11 /* distinct */
8 ReturnNode 0 - RETURN #13

Steps to reproduce
- Just run the AQL query
Problem:
Whole ArangoDb instance crashes, i.e. I need to manually restart the ArangoDb service.
Expected result:
Load data
