-----------------------------
Summary: Make DatasetGraphMonitor transaction-aware
Key: JENA-1656
URL: https://issues.apache.org/jira/browse/JENA-1656
Project: Apache Jena
Issue Type: Improvement
Components: ARQ
Affects Versions: Jena 3.10.0
Reporter: Pip Cet
In order to implement continuously-updated query result streams, I used a
DatasetGraphMonitor to monitor when the relevant part of the dataset graph
changed in order to re-run the query. However, there was a race condition
because DatasetGraphMonitor informs its monitor of uncommitted changes; the
query would be repeated too soon, meaning the changes would be missed.
Adding the commit() method to the DatasetChanges interface and using it seems
to avoid this issue.
