[jira] [Comment Edited] (JENA-1236) Failure during query in
restarted Fuseki server (inference)
[ https://issues.apache.org/jira/browse/JENA-1236?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15493140#comment-15493140 ]

---------------------------------------------------------------
{{DatasetGraphMapLink}} isn't passing down the pseudo-commit in any way. It should at least call {{ARQ.sync}} on all graphs. Given the composite ad hoc nature of {{DatasetGraphCollection}} (the purpose of this and the super class), it will not be a perfect commit in all cases.
Also, the case of graphs, an inf graph, over a database, may be worth pulling out and handling specially.
