Svante Schubert updated TINKERPOP-2008:
---------------------------------------
Description:
I could only reproduce the problem of duplicated IDs in the graph output after
a query on the Gremlin console if it was a larger/complex input file and only
if both GraphML import and export were being used.
If I loaded the file as identical Gryo file the export was without duplication.
I assume there are some thresholds/memory dumps where you might compare the RTM.
There 7 edges with duplicate IDs in the following lines of the attached file
'output__in_table-table_graphml.graphml'
Line 736: Duplicate unique value [370] declared for identity constraint
"edge_id_unique" of element "graph".
Line 758: Duplicate unique value [374] declared for identity constraint
"edge_id_unique" of element "graph".
Line 783: Duplicate unique value [378] declared for identity constraint
"edge_id_unique" of element "graph".
Line 797: Duplicate unique value [382] declared for identity constraint
"edge_id_unique" of element "graph".
Line 818: Duplicate unique value [386] declared for identity constraint
"edge_id_unique" of element "graph".
Line 854: Duplicate unique value [390] declared for identity constraint
"edge_id_unique" of element "graph".
Line 887: Duplicate unique value [400] declared for identity constraint
"edge_id_unique" of element "graph".
In addition, the problem is related to the query. If I load and save the Graph
immediately no edge problem occurs.
